A SIMPLE IDEA
You don’t need to be a chess player. Just learn how each piece moves and bring a good idea.
Drag pieces onto the board. Each one covers the squares it can attack.
Reach every playable square, including those already occupied by a piece.
Every piece has a cost. Use fewer points and work towards the board’s target.
TWO WAYS TO THINK
The same goal, two ways to read the board. Choose a mode and compare.
Place pieces without the legality restrictions of Advanced mode. Explore combinations, learn their attacks and find a more efficient solution.

Add placement and piece-composition rules. Coverage is still your goal, but you’ll also need to build a valid position.

MAKE TIME FOR STRATEGY
Fresh boards every day, five levels in each mode and room to improve at your own pace.
Start with levels 1, 2 and 3 in each mode, free. Levels 4 and 5 unlock with Premium.
Match or beat the board’s target. Solving it is the start; using fewer points is the challenge.
Follow your streak, check your statistics, unlock achievements and share your results.

Four palettes, white or black pieces and animation settings to make yourself at home.
The interactive tutorial walks you through coverage, controls and scoring, one step at a time.

BEFORE YOUR FIRST MOVE
You don’t need experience playing chess matches. The pieces keep their familiar moves, and the interactive tutorial teaches you how to use them to cover the board.
Fewer points is better. Each piece has a cost: queen 9, rook 5, bishop 3, knight 3 and pawn 1. Your challenge is to cover every playable square with an efficient combination.
Find a valid solution with a score at or below the board’s target. If you solve it with more points, you earn one or two stars depending on how close you are to the target.
Levels 4 and 5 in Basic and Advanced, plus the full calendar of the last 30 days. You can start for free with levels 1 to 3 in each mode.
