Sudecku
Sudoku meets deck building
What if solving Sudoku meant playing your cards right?
Sudecku combines the challenging logic of Sudoku with strategic deck building, where you play cards from your hand to fill cells.
Don't have the card you need? Draw from your deck or get creative. Power cards let you peek at possibilities, undo mistakes, or auto-fill cells, but they cost you score points.

Daily Puzzle
Core Mechanic
Play cards to solve puzzles
Forget regular Sudoku where you can fill any cell once you figure out the number. In Sudecku you play cards from your hand. Got a 7 card? Great, you can place a 7. Don't have the card you need? Better draw from your deck or get creative.
This simple constraint creates surprisingly tough decisions and forces you to think strategically about which cells to fill and when.
Strategy
Power cards and resource management
Power cards let you peek at possibilities, undo mistakes, or even auto-fill cells. The catch? They cost points. So now you're juggling logic puzzles AND resource management.
Build your perfect deck by solving puzzles and earning rewards. Unlock new power cards and mix them until you've got a deck that matches your playstyle—aggressive, defensive, or chaotic.
