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.

Keep going — fill every cell with no clashes.
Ready to freeze the board?
6 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 24 moves — a wrong answer costs one too.
Careful: 5 wrong answers end the mission.
