Every board is winnable. Prove it in par.
Color Flood is a flood-fill puzzle game by SoftMobiXBD. You start in the top-left corner of a coloured grid and pick a colour; every tile touching your region that matches turns with you. Keep choosing until the whole board is one colour — and do it inside the move budget.
It is a simple rule with a deep strategy, and version 2.0 rebuilds the game from scratch around one idea: the puzzle should be hard, never unfair.
Boards are not simply randomised. Each one is generated and then handed to a solver; if the solver cannot clear it inside the move budget, the board is thrown away and another is generated. A 500-board automated test enforces this on every code change. You will never again lose to a board that could not be won.
A beam-search solver computes a near-optimal move count — the board's par — and your stars are awarded against it. Clearing a board is the easy part. Clearing it in par is the game.
Version 1 shipped a 22×22 board with a 38-move budget. A near-optimal solver needs about 41 moves on average, so the hardest difficulty was unwinnable roughly 78% of the time — and nothing in the game told you. That is the bug version 2 was built to kill.
All 12 palettes are validated for perceptual separation — every pair of colours on a board is at least ΔE 22 apart in CIE-Lab space, with a guaranteed spread in lightness. For players who need more, colourblind mode draws a distinct glyph (● ▲ ■ ◆ ★ ✚) on every tile, so colour never carries the information alone.
| Mode | What it is |
|---|---|
| Journey | A ladder of seeded levels. Stars unlock what comes next, and the grid grows every 20 levels. |
| Daily Challenge | One board per day, seeded from the date, identical for every player in the world. Build a streak — and keep it. |
| Zen | No move limit, no fail state, endless boards. For when you want the puzzle without the pressure. |
Four tiers. The grid grows; the six colours never change. The move budget is calibrated against simulated play — generous enough that a planned game wins about 97% of the time, tight enough that tapping without thinking loses.
| Tier | Grid | Moves |
|---|---|---|
| Relaxed | 10 × 10 | 22 |
| Steady | 14 × 14 | 30 |
| Sharp | 18 × 18 | 39 |
| Ruthless | 22 × 22 | 47 |
Every effect is synthesised on a C major pentatonic scale, one pitch per palette slot, so fast tapping stays musical instead of turning into noise. The flood sound even changes pitch with the size of the region you just captured.
Color Flood is completely free. There are no banner ads, and an ad will never interrupt a puzzle in progress. You can choose to watch a reward video for extra moves — every board is winnable without one — and now and then a short ad plays after you win a board, never more than one every few minutes.
The game needs no account, no sign-in, and no internet connection to play. Your progress stays on your device. See our Privacy Policy and Terms of Use.
Color Flood is rated for players aged 13 and up. It suits anyone who likes a clean, thoughtful puzzle — whether that means two minutes on a Daily Challenge or a long, quiet run at a 22×22 board.
