About Color Flood
Color Flood is a connected-region planning puzzle. Change one corner region at a time to turn the complete board into one color.
The choices create a tradeoff between immediate area and future access. Every board is generated here by original code, without copied levels or artwork.
How to play Color Flood
- 01Start with the connected region in the top-left corner. Pick a different color to recolor your region and absorb matching cells touching it above, below, left or right. Diagonal contact does not count.
- 02Each different-color choice costs one move, even if it gains no cells. The current color is disabled. Fill the whole board to win; using the final move without filling it ends the attempt.
- 03Small uses 6×6 cells and four colors, Medium 10×10 and five, Large 14×14 and six. Every new board has a complete legal solution within its budget; the budget is not a claim of optimal play.
- 04Undo can reverse a win or a loss. Restart retries the same board. New board creates a fresh random puzzle. This is repeatable single-board play, without numbered campaign levels.
Color Flood controls
- Pick a color
- Click or tap one of the numbered swatches below the board. Keyboard users can Tab to a swatch and use Enter or Space.
- Revise a plan
- Undo restores the previous legal board, including after a win or loss. Restart keeps the initial board and move budget.
- New challenge
- Choose a size or New board. The current legal history saves locally when browser storage permits it.
Color Flood: levels and progress
There are no numbered levels. Small, Medium and Large use 6×6 / 10×10 / 14×14 cells and four / five / six colors. New board generates another random puzzle.
The budget is a verified greedy solution length plus three, two or one spare moves respectively. It guarantees a route, not the shortest solution or a strict difficulty ranking between random boards.
Color Flood tips and strategies
Build a bridge
A small adjacent patch can connect you to a large cluster of the same color on the next move. Look one step beyond the immediate boundary.
Consolidate distant colors
Try to bring two separated regions onto your frontier before choosing their shared color. One move may then absorb both.
Review the finish
If only two colors remain, inspect their connected components before spending a move. Undo lets you compare a different order.
- A narrow color bridge may reach several regions next turn. Compare it with the biggest immediate gain.
- Avoid spending turns on isolated colors that do not touch your region.
- Numbers identify colors as well as the swatches; the top-left ring marks your starting territory.
Color Flood FAQ
Are all boards solvable?
Yes. A complete constructive route is checked before the move limit is set. There can be shorter routes.
Does it save?
The current board and legal history resume in this browser if storage is available. New board replaces that current save.
Can I color any cell?
No. Only the region connected to the top-left corner changes color. The board cells are a visual map; the numbered swatches are the controls.
What happens at zero moves?
An incomplete board ends in a loss. A complete board wins even on the final permitted move. Undo can resume play.
Is this multiplayer or a daily leaderboard?
No. This version is single-player with random boards and browser-local saving.
