Break all the ice — you do not have to finish the grid. Correct digits near a block crack it.
Fill in the digits 1 to 9 so that no digit repeats in any row, any column, or any 3×3 box.
Tap a cell, then tap a symbol to fill it (or type). Clashing cells turn red.
How to play: Fill in the digits 1 to 9 so that no digit repeats in any row, any column, or any 3×3 box.

Keep going — fill every cell with no clashes.
Ready to freeze the board?
10 blocks of ice will land on the grid. Every correct digit in the same row, column or box cracks the ice near it — and a block left as the LAST empty cell of its row, column or box explodes on its own. Break them all!
🔢 You get 45 moves — a wrong answer costs one too.
Careful: 3 wrong answers end the mission.
