Mahjong Relax is mahjong solitaire without pressure: no clock, no score chase, just a layout of tiles and as long as you want to clear it.
The format suits that treatment. Without a timer, mahjong becomes a planning puzzle — which pair you take first genuinely decides whether the board stays solvable.
No — that's the point. It's built as an untimed, calm version of mahjong solitaire.
Prioritise tiles that unblock several others, and don't match a pair if it leaves the other two of that type stacked on each other.
Yes — tap to match. Nothing to install.
