Pixeloku is a color-based logic puzzle. Fill in the empty cells so that each row, column, and 3x3 section contains every color exactly once. Use logic to deduce the correct placement - no guessing required!

There are six difficulty levels based on how many cells are pre-filled:
Beginner: 41 cells filled - great for learning
Easy: 38 cells filled
Medium: 35 cells filled
Intermediate: 32 cells filled
Hard: 29 cells filled
Extreme: 26 cells filled - for experts only

Classic: Traditional gameplay at your own pace with no restrictions
Adventure: Progress through 100+ handcrafted levels across multiple chapters, earning pixel rewards and unlocking themes
Daily Challenge: A new puzzle every day - build your streak!
Timed: Race against the clock and earn bonus points for quick completions
Moves: Complete the puzzle within a set number of moves
No Mistake: A single wrong placement ends the game - perfect for experts
Rush Hour: Cells disappear over time - solve before they're gone
Blocked: Some cells start locked - unlock them by solving adjacent cells
Endless: Unlimited puzzles with no hints and no undo - pure challenge
Follow the Leader: Colors must be placed in palette order - the game guides you through each color one at a time
Shapes: Place colored shapes on the board - find where each piece belongs
Ghost Race: Race against the fastest player's time for each difficulty - beat the ghost to set a new record
Links: Cells connect like chain links - solve one cell and watch it chain-solve linked neighbors automatically
Fog: Some clues hide in the fog - place colors nearby to clear the fog and reveal hidden pre-filled cells
Memory: Like the classic card game - tap two cells to reveal colors, matching pairs auto-fill permanently
Paper: Solve like on paper - no feedback until you're done. Erase any color you placed and use hints to see which placements are wrong
Random: Let fate decide - game mode, difficulty, and theme are all randomized

Pixels are the in-game currency. Earn them by completing puzzles, winning games, and reaching milestones. Use pixels in the store to purchase hints and unlock new color themes.

Hints reveal the correct color for a single cell. You can earn hints by playing games and spending pixels, or through Adventure Mode rewards. Hints are available in most game modes except Endless.

The store offers hints and color themes. Spend your earned pixels to unlock beautiful new color palettes for your puzzles, or stock up on hints for when you need them.
