way of playing (a game)

  • The upper left area (the area connected by the same color as the current color) is "your area
  • Clicking on the color button below will change the entire area to that color, and will bring in adjacent squares of the same color.
  • If all the squares are unified with one color, it is clear!
  • Please clear the game before the number of moves remaining reaches zero (within 25 moves).
  • Tip: It is more efficient to choose the most widely adjacent color

What is Color Flood?

Color Flood is a puzzle game where you flood-fill a grid starting from the top-left corner by selecting colors to paint adjacent matching squares. Each move changes your starting square's color to a new color, and all connected squares of the original color transform with it. The challenge is reaching all grid squares within a limited number of moves. It combines strategy, planning, and spatial reasoning as you navigate expanding color regions across the board.

How to Use

Begin with the top-left square highlighted. Select a color from the available palette at the bottom. Your square and all adjacent squares matching the original color instantly change to that new color, expanding your controllable region. Observe which colors border your expanding region—these are optimal next moves since they'll absorb additional squares. Continue selecting colors strategically, watching your colored region grow and merge. The game tracks remaining moves; complete the puzzle by coloring all squares before exceeding the move limit. Later levels introduce more colors and larger grids.

Use Cases

Puzzle game entertainment: Enjoy short, engaging play sessions during breaks. Brain training: Exercise planning and spatial reasoning skills by anticipating color sequences. Pattern recognition practice: Identify optimal color paths by predicting grid expansion. Logic puzzle engagement: Challenge yourself with progressively harder difficulty levels. Casual strategy gaming: Play at your own pace without time pressure or competition.

Tips & Insights

Plan multiple moves ahead: Identify which color will create the most expansion, not just the immediate next move. Avoid corner squares: Filling corners first limits expansion since corners have fewer adjacent squares. Look for bottlenecks: Colors blocking your expansion should be prioritized. Larger regions are stronger: Growing one large region is often better than spreading across multiple small regions. Study completed puzzles: Understanding optimal solutions improves your strategic instincts for new boards.

Frequently Asked Questions

How to play?

Clicking on the color button below will change the upper left area to that color, and the area will expand to include adjacent squares of the same color. The entire area is cleared when it is all one color.

What is the number of moves limit?

The game must be cleared within 25 moves. The fewer the number of moves, the higher the score.

Do the puzzles change every time?

Yes, we start with a random color scheme each time.

Tips?

Prioritizing colors adjacent to large clumps will help spread them out more efficiently.

What's the optimal strategy to solve puzzles faster?

Plan your moves 2-3 steps ahead, starting from corners to maximize the spread. Avoid getting trapped in small regions—expand aggressively early on. Watch for color bottlenecks (single tiles that block progress) and prioritize breaking them.

Are all puzzles solvable within the move limit?

Yes, puzzles are algorithmically generated to be solvable. However, the move limit varies by puzzle difficulty—harder puzzles have tighter limits. If you can't solve it, try a different sequence; often a 1-2 move difference exists between optimal and suboptimal solutions.

How is the score calculated, and what counts as a high score?

Typically, scores are based on moves remaining (fewer moves = higher score) and time elapsed (faster = higher bonus). An excellent score means you solved the puzzle near the theoretical minimum moves while solving quickly.

Does every playthrough have different puzzles?

Yes, puzzles are randomly generated each time, ensuring fresh challenges. However, some games also include hand-crafted puzzle sets for variety. If you encounter the same layout twice, it's coincidental—the grid size and move limits are randomized.

How does difficulty level affect puzzle generation?

Easy levels have more neutral colors and larger initial regions, making it faster to spread. Hard levels have more fragmented color regions and tighter move limits. Very hard levels might introduce rare colors that appear only once, requiring precise sequencing.

What's the relationship between grid size and puzzle difficulty?

Larger grids (10x10 vs 8x8) mean more squares to fill, requiring more moves and time. However, difficulty is primarily controlled by color fragmentation and move limits. A 6x6 puzzle with tight constraints can be harder than a 10x10 with loose limits.
