About This Game

Sudoku, but it pops. Every right digit pops into candy and pays Digits. Lock rows, columns and boxes for chains, build your combo into Fever, and spend it all on bigger boards and better tools.

Hire Your Numbers

Each digit from 1 to 9 has a builder with a face and a meter. Hire them and level them up, and they drop candies onto the board while you think. Flip the board to play alongside them on a co-op board, or keep the front to yourself.

Boards Made of Boards

Evolve your builders and they work further out. Every finished 9×9 becomes one cell of a Mega board, Megas fill Giga boards, and so on up to Omega. In the late game, millions of Sudokus a second roll past in TURBO, HYPER, ULTRA and OVERDRIVE.

Pop for Stars

When your run is big enough, Pop it. Your Digits turn into Stars, which you spend on the Star Board (itself a Sudoku). Finished lines there unlock perks like Auto-Builder and Head Start.
