Tenfold is a number merge puzzle for iPhone and iPad. Drag shapes from your tray onto the grid. Neighbouring tiles with the same number merge into a bigger number, and any group that adds up to exactly 10 clears. The run ends when nothing else fits. Play is endless: as your score climbs, the Heat Level rises and brings trickier shapes and ice blocks. Chain clears for combo multipliers. Fully offline, with dark and light modes and haptics. Free with ads.
