Classic Sudoku, played in color.

Tap a space, then a color. Double-tap a color to lock; tap the locked color to unlock. Keyboard: arrows to move, 1–9 to place, Delete to erase.
How to play
1. Pick a puzzle. Choose Easy, Medium, or Hard, then New puzzle. Starting pieces are placed automatically and stay locked.
2. Fill the board. Select an empty space, then choose a color. Every row, column, and 3 × 3 box must contain all nine colors exactly once.
3. Narrow it down. Find a nearly full row, column, or box. Which color is missing? Scan the intersecting row and column to rule out spaces.
Try notes. Turn Notes on to record possible colors in a space. Turn it off to place your answer. Show numbers adds a consistent 1–9 color key.
Need a hand? Check compares your placed colors with the solution. Hint fills one space. Using any hint makes this puzzle ineligible for the shared leaderboard, even after undo or reload. Undo reverses a move. Palette counts show how many of each color are placed.
The high scores.
