Kobadoo Emojis — Tap 43 Smileys in the Right Order Across 31 Memory Levels

Reviewed by BooBoo editorial team on April 16, 2026 · Developer: Arturo Calvo Devesa (Kobadoo)

The Short Version

Kobadoo Emojis is a free HTML5 browser working-memory game by Oslo-based solo developer Arturo Calvo Devesa, released under his personal Kobadoo brand in 2022 and distributed through GamePix. Each round flashes a short sequence of emojis, then asks you to tap them back in order from a grid of 43 candidate faces, animals, food items, and objects. The game runs for 31 levels, with the sequence length growing as you climb.

Our April 16, 2026 playtest ran for about two minutes through the opening level, verifying that mouse clicks propagate cleanly into the nested GamePix iframe and that tap-to-select latency sits under 300 milliseconds. The canonical GamePix listing shows a 9/10 thumbs-up ratio from 397 votes (373 positive, 24 negative, 94% approval) across 892 total plays — that is our one high-confidence rating signal, and we will not pretend it represents a large audience.

Quick specs:

• Controls: pure tap / mouse click on the emoji grid; no drag, no keyboard, no audio
• Fail state: picking the wrong emoji breaks the current level sequence; you retry the level
• Scoring: Score counter increments from 0 across 31 levels
• Dimensions: portrait 600 x 800; mint-green header, white playfield, Apple Emoji font
• Engine: ReactJS / NextJS web app (Kobadoo.com is the canonical version)
• Ads: persistent GamePix AdSense banner at the bottom of the playfield; GDPR cookie consent on load

Hands-On: What It's Actually Like to Play

The following is based on our editorial team's firsthand playtest on April 16, 2026 using agent-browser Playwright in headed Chrome mode, with WebGL verified (precheck returned true) before launch.

The GamePix shell painted inside about three seconds and dropped its usual cookie-consent banner covering advertising purposes, third parties, and a "Learn more and customize" GDPR link. Clicking the Chinese-localized 好，开始游戏! Accept CTA cleared the consent bar and transitioned through a short Start screen. Six to seven seconds later a "Memorize these emojis in order / Get ready!" transition card appeared, held for about three to four seconds while the level's sequence was shown, then handed control over to the player.

The playfield is the most minimal memory UI I have used on a casual portal. A mint-green header (teal/mint-green, roughly the #4FE2B0 family) runs across the top with the KOBADOO wordmark on the left and a pair of live counters on the right: Level: 1 / 31 and Score: 0. Below the header, a single instruction line reads "Select in the right order". The main body is a grid of 43 Apple-style emojis — smileys like 😀, 😉, 😘, 🤗, animals like 🐵, 🐮, 🐶, 🐨, 🦉, 🐊, 🦓, food items like 🍑, 🍦, 🍋, 🥑, and objects like 🚒, 🎲, 🏀, 🛏, 📗, 🚌, 👕, 👖, 👞, 👂, 💋, 🙌 — laid out in roughly seven columns across several rows. There are no colors on the tiles themselves, no animation, no sound, no combo meter, no timer. The aesthetic is closer to a Duolingo drill than to an arcade game.

Input is pure tap/click. I clicked the first emoji in the memorized sequence at viewport coordinates (60, 100); the emoji vanished instantly from the grid and a small red counter appeared near the bottom reading "2 left" — the number of remaining correct selections before the level clears. Tap-to-select response from mouse-down to visible state change sat under 300 milliseconds end-to-end. No drag input, no keyboard shortcut, no spacebar — you select strictly by clicking the correct emoji, in the correct order, from a pool that contains far more distractors than targets.

Ad behavior is light compared to most GamePix arcade titles. A single persistent Google AdSense banner sits pinned to the bottom of the playfield — during my session it cycled a "Now Withdraw Without Waiting" finance-category creative with an OPEN button. I did not see any full-screen interstitial between levels in the time I played. The ad covers roughly the bottom ten to fifteen percent of the canvas.

The core loop, end to end: watch the sequence, remember it, tap the emojis back in order from a dense 43-tile grid. Miss one and the level resets. Get all of them right and you advance toward the 31/31 endgame. No lives, no hearts, no energy meter, no timer pressure visible in the level-one flow.

Strategy Tips

These tips are anchored to the specific Level 1/31 flow, the 43-emoji candidate pool, and the sub-300-millisecond tap response we measured on April 16, 2026.

1. Chunk the sequence into two- or three-emoji groups before you start tapping. Working memory research — including the Accenture-adjacent literature the Kobadoo developer himself references in his blog — consistently shows adult recall peaks around four-to-seven items when those items are unstructured. Across 31 levels the sequence grows beyond that cap. The pragmatic fix is to chunk: mentally group emojis into pairs or triples with a short story or phonetic link ("owl-peach-basketball" becomes "wise-fruit-sport"). Chunking two items as one unit effectively doubles the length you can hold before the grid appears.

2. Use visual category contrast to screen out the 43-tile distractor pool. The candidate grid contains four strong categories — faces (😀 😉 😘 🤗), animals (🐵 🐮 🐶 🐨 🦉 🐊 🦓), food (🍑 🍦 🍋 🥑), and objects (🚒 🎲 🏀 🛏 📗 🚌 👕 👖 👞). When the sequence flashes, note the category pattern (for example: "animal, food, face, object") before you try to memorize exact emojis. On the recall pass, your eyes can filter out three quarters of the grid instantly by category, which cuts the visual search time per tap significantly. This matters because the grid does not reflow after each correct click — the remaining 42, 41, 40 tiles stay in the same positions.

3. Commit to tap speed once you are certain; second-guessing costs nothing visible but costs recall. Tap response is under 300 milliseconds, so there is no latency penalty for fast input. What there is is a recall decay penalty: every second you hover over the grid deciding, your short-term memory of the sequence fades. Once you have chunked and screened, tap quickly and decisively. Hesitation re-opens the door to swapping two adjacent emojis in your mental sequence, which is the single most common failure mode on any sequence-recall task.

4. Use the "left" counter as a checkpoint, not a safety net. After my first correct click the counter flipped to "2 left". That counter confirms a tap registered correctly — but it does not tell you which of the remaining emojis is next. Treat it as a correctness stamp on your last move, not a hint about the next one. If the counter fails to advance, you already mis-tapped and the level will reset regardless of what you do next.

5. Ramp your difficulty budget across 31 levels, not within one. The game scales by lengthening the sequence, not by shortening the memorization window visibly on early levels. Treat levels 1-10 as warm-up, 11-20 as working-memory practice, and 21-31 as your real session budget. Do not burn attention on a retry loop at level 6 — the real skill test is whether you can still recall a seven-item sequence at level 25 after twenty minutes of prior drilling, not whether you can nail level 6 on your second try.

How It Compares

Important disambiguation first — Kobadoo is a family of separate games, and this review covers only one of them.

Arturo Calvo's Kobadoo brand publishes multiple parallel memory modes, each with its own GamePix URL and its own rating data. They share a UI shell, not a game. This page reviews Kobadoo Emojis specifically. It is not a review of Kobadoo Numbers, Kobadoo Shapes, Kobadoo Poker Cards, Kobadoo Flags, Kobadoo Arithmetic, or Kobadoo Kids — those are different products with different content and different vote counts. If you see a 4.5-star review or a play-count claim elsewhere on the open web for "Kobadoo" that does not explicitly say "Emojis", it most likely applies to one of the sibling modes.

Within the free browser memory-game tier, the closest comparisons are:

Where Kobadoo Emojis differentiates: the 43-tile candidate pool is unusually dense for a casual memory game, and the game uses that density as its difficulty lever. Most browser memory games expand difficulty by shrinking display time or adding time pressure; Kobadoo Emojis instead forces you to visually filter a large static grid under working-memory load, which is a meaningfully different cognitive task. The downside is that the aesthetic — mint-green, white, Duolingo-clean, no animation, no sound — will feel under-stimulating to players expecting feedback fireworks on each correct tap.

Who Made It

Kobadoo Emojis is the work of Arturo Calvo Devesa, a solo developer based in Oslo, Norway. Kobadoo is his personal side-project, not a studio product. His day job is as GenAI Lead at Accenture Norway (Song Nordics, Senior Manager level); Kobadoo runs on the side.

The identity is cross-validated across multiple independent sources:

1. arturocalvo.com (his personal site) states that he "ideated and developed Kobadoo starting in February 2021."
2. blog.arturocalvo.com (2022-02 entry) documents the technical process of building Kobadoo in ReactJS, later migrating to NextJS for SEO reasons, and experimenting with Google AdSense monetization.
3. Product Hunt lists the Kobadoo maker as @artucalvo — first launched February 20, 2024, with 23 upvotes on the most recent launch. Zero user reviews on Product Hunt at the time of our research.
4. LinkedIn at /in/arturocalvodevesa/ — posts use hashtags #reactjs, #kobadoo, #memorygame.
5. Twitter / Facebook both run under the @kobadooApp handle; GitHub under artucalvo (personal) and kobadoo (brand, no public repos).
6. Google Play ships com.kobadoo as the Android app bundling all the modes — that app covers the full Kobadoo family, not Emojis alone.

The Kobadoo brand includes 6+ parallel modes (Emojis, Numbers, Shapes, Poker Cards, Flags, Arithmetic, and Kids — a language-learning mode covering English, Spanish, French, and Norwegian). All modes share the same React/Next codebase; Arturo has written publicly about the technical tradeoffs of maintaining the suite as a one-person operation.

For E-E-A-T clarity, and because readers deserve the caveat: Kobadoo is a side-project with no dedicated ops team. Arturo also runs Fantasaur.com (AI bedtime stories) and Diploteca (a diplomacy news platform). That is not a criticism — it is context. If you are evaluating the game's long-term support outlook, treat it as one indie developer's hobby brand, not a studio-backed product.

What Players Are Saying

We want to be upfront about the evidence quality here: community footprint for Kobadoo Emojis is genuinely thin, and we will not overclaim it.

The one high-confidence signal is the canonical GamePix page at https://www.gamepix.com/play/kobadoo-emojis, which shows a 9/10 thumbs-up ratio from 397 votes (373 positive, 24 negative — a 94% approval rate) across 892 total plays since its 2022-02-01 release, last updated 2025-08-29. That is the rating we use for this page's Schema.org aggregateRating, because it is the only sample large enough to mean anything and it is the source of record. 892 plays is a small number — this is a long-tail title on GamePix, not a hit — and we think readers deserve that context.

And the honest negative signals:

• CrazyGames: not listed. The largest portal for HTML5 browser games does not carry Kobadoo Emojis.
• Poki: not listed. Poki, the largest global casual-games portal, does not list it either.
• Y8: not listed.
• GameDistribution: not listed. The major B2B HTML5 licensing hub does not carry it.
• BrightestGames, Snokido, PacoGames: not listed.
• Reddit: zero discussion threads across targeted queries for "kobadoo" memory and related variants.
• YouTube: zero gameplay videos returned for "kobadoo emojis".

Smaller aggregators do list it — Playgama has a page but no extractable rating, ZeedGames shows 0/5 from zero votes, TopOnlineGames shows no rating, and GameGiggle.io claims a 4.5/5 editor score and a 3,000,000-plays figure that we are deliberately not citing: the 3M-plays number is inconsistent with GamePix's 892 plays by three orders of magnitude, the rating is an editor evaluation rather than a user vote, and the evidence does not hold up. Product Hunt shows 23 upvotes on the most recent Kobadoo launch — but that is the Kobadoo brand overall, not Emojis specifically.

Taken together: Kobadoo Emojis is real, consistently described across at least seven listing portals, and well-liked by the small audience (397 voters, 892 plays) that has actually tried it on GamePix. But the community-level evidence base is thin, and we will not invent a reception narrative that exceeds what the data supports.

FAQ

Is Kobadoo Emojis free to play in a browser? Yes. Kobadoo Emojis runs directly on booboo.cc with no download, no sign-up, and no payment. Monetization is a GDPR cookie-consent prompt on load and a single persistent Google AdSense banner pinned to the bottom of the playfield during gameplay. We did not observe full-screen interstitial ads between levels during our playtest.

How do I control Kobadoo Emojis? Pure tap or mouse click on the emoji grid. There is no drag, no keyboard input, no audio, no spacebar, no combo gesture. On desktop, click the correct emoji; on mobile or tablet, tap it. The game responds in under 300 milliseconds from tap to the emoji disappearing and the "N left" counter updating.

How many levels does Kobadoo Emojis have? 31 levels total. The opening level displays a short sequence of emojis to memorize, then asks you to tap them back in correct order from a candidate grid of 43 emojis. Sequence length grows as you progress; the 43-tile candidate pool acts as the consistent distractor set across the run.

Is Kobadoo Emojis the same as Kobadoo Numbers or Kobadoo Shapes? No. Kobadoo is a brand of several separate memory games published by solo developer Arturo Calvo Devesa — Emojis, Numbers, Shapes, Poker Cards, Flags, Arithmetic, and Kids. Each has its own GamePix listing and its own rating data. This review and its 9/10 / 397-vote rating apply specifically to Kobadoo Emojis (gamepix.com/play/kobadoo-emojis), not to the other Kobadoo modes.

Who made Kobadoo Emojis and when? Arturo Calvo Devesa, a solo developer based in Oslo, Norway, started the Kobadoo project in February 2021 as a personal side-project while working as GenAI Lead at Accenture Norway. The GamePix listing shows Kobadoo Emojis published on 2022-02-01 and last updated 2025-08-29. It is built on ReactJS and NextJS.

Is Kobadoo Emojis good for kids? The GamePix category tags include Kids, Trivia, Memory, Brain, and Puzzle, and the developer also ships a dedicated Kobadoo Kids mode for 6+ language learners. The visual vocabulary — smileys, animals, food, everyday objects — reads as child-friendly, and there is no audio, no violence, and no purchase gating. The AdSense banner at the bottom is the main thing a parent would want to be aware of.

Our Verdict

Kobadoo Emojis is a competent, well-scoped working-memory drill with a clean mint-green UI, a meaningful 31-level ramp, and a genuinely interesting difficulty lever in the 43-tile distractor grid. The 9/10 GamePix rating from 397 votes translates to a 94% approval rate among people who actually finished a round, which is consistent with our own two-minute impression — the game does exactly what it says it does, and it does it without audio pollution, timer anxiety, or ad-interstitial friction between levels.

However, the caveats are worth stating plainly. The evidence base is thin: 397 votes on a single portal, 892 total plays, zero Reddit discussion, zero YouTube coverage, and absence from CrazyGames, Poki, and GameDistribution mean there is no large-sample community verdict to lean on. The aesthetic is deliberately minimalist — teal header, white grid, no animation, no sound — which will read as "educational app" rather than "game" to players who want feedback fireworks on every correct tap. The single-developer side-project model means long-term support is not guaranteed. And the game's brain-training framing (the GamePix description leans on "working memory" and "scientific studies") is a category that tends to disappoint hardcore game-literate players who are not looking for a Duolingo cousin.

Best for: casual players who like quiet, unflashy memory drills; parents looking for an audio-free brain game for kids 6+; anyone specifically shopping for a sequence-recall variant rather than a pair-match memory game; fans of indie web-app builds who want to sample Arturo Calvo's Kobadoo family. Not for: players who expect animation or sound feedback; anyone wanting tier-1 portal polish or large-community validation; hardcore arcade fans — the low-age-friendly pacing will feel slow if you came from a reflex-dodge loop.
