SteelGrid Collection

Drop blocks, clear lines, chase the high score. The classic that started it all.

Toggle lights to turn them all off. Every move flips the neighbouring cells too — think before you switch.

Place one star per row, column and coloured region without any two stars touching. Pure deduction.

Use number clues to fill the correct cells row by row and column by column. Classic nonogram logic.

Place satellites next to antennas using row and column clues. Each antenna gets exactly one satellite — find where every signal connects.

Merge tiles, reach the ultimate number. Simple rules hiding deep strategy.
