What Is Color Flood?
Color Flood is a compact strategy puzzle played on a board of colored squares. Your starting territory sits in the upper-left corner. On each turn, you pick a new color; your territory changes to that color and absorbs any matching squares that touch it along an edge. The goal is to make the entire board one connected territory before the move counter reaches zero. The puzzle is easy to understand, but choosing an efficient route takes a little planning.
How to Play Color Flood
Start by looking at the square in the top-left corner. That square, and any same-colored squares connected to it horizontally or vertically, form your first region. Choose one of the color buttons beneath the board. Every square in your region changes to the color you chose, then any neighboring squares of that color join the region. The newly expanded region can now reach more squares on later turns.
Continue choosing colors until the whole board belongs to your region. You cannot choose the color you currently have, because doing so would not expand the board. Each valid color choice uses one move, even when it absorbs several separate-looking patches at once. Diagonal contact does not count: two squares connect only when they share a side.
Color Flood Game Rules
The game tracks the cells connected to the top-left starting region. A move recolors that entire region and adds every touching cell with the selected color, including matching cells reachable through other newly added cells. The game checks the board after each move. You win as soon as all cells are in the region. If the move limit is reached first, the round ends and you can retry the same layout or start another board.
Every standard board has a fixed size, color set, and move limit. Easy is a 10 × 10 grid with four colors and 18 moves. Medium is 14 × 14 with five colors and 30 moves. Hard is 18 × 18 with six colors and 44 moves. A win score uses a difficulty base of 300, 600, or 1,000 points, then adds 20, 35, or 50 points per unused move for Easy, Medium, or Hard. A lost round receives no completion score. Your personal best is saved on this device.
Tips and Strategies to Win
- Look ahead before choosing. Check the colors touching your current region and consider what each choice could expose next.
- Think about connections. A color may appear in multiple places, but only matching squares reachable from your region through shared edges will join.
- Notice larger patches. A move that connects to a broad area can be more useful than a move that picks up one isolated square.
- Keep future access in mind. A smaller gain can open a path toward a larger patch of another color on the next turn.
- Use the move counter. Check how many moves remain and avoid spending one without a reason. You can pause to study the board without a timer.
- Plan flexibly. Several colors may offer similar gains. Choose a promising route, then adjust as the flooded region reveals new options.
Choose Your Difficulty
Easy is a smaller board with four colors, giving new players a comfortable place to learn how the connected region grows. Medium adds more cells, another color, and a tighter move budget. Hard offers the largest board and six colors, so there are more possible routes to consider. These settings change the board and the points awarded for a win; the game has no timer, so you can take the time you need.
Why Play Color Flood?
Color Flood makes a satisfying short break: each turn is simple, while the order of your choices shapes what becomes reachable later. You can play casually or focus on completing a board with moves to spare. It is a recreational puzzle about observation and planning, without claims about guaranteed effects on health or intelligence.
