You sit down for a quick break, open a mahjong board, and ten minutes later you are stuck staring at tiles that all seem blocked. Online Mahjong Harmony is a mahjong solitaire layout built around that exact tension: a board where the order you clear tiles matters.

Key features
A three-layer board that rewards planning
The tiles are stacked in three different layers, so you have to look ahead to decide which tiles to clear first. Grabbing the first match you see can bury a tile you need later.
Flower and season tiles match within their group
You clear the board by clicking matching pairs. Flower tiles match any other flower tile, and season tiles match any other season tile. The numbers shown in the right corner help you spot them.
Shading that shows which tiles are playable
The site shades tiles that are currently unplayable and highlights the playable ones when you hover over them. You waste fewer clicks on blocked tiles.
A saved record score to beat
Your record score is saved automatically every time you play, so each new game has a number to beat.
Who it's for
It suits you if you already know basic mahjong solitaire and want a layout with a bit more thinking than a beginner board. It also suits you if you like to play instantly in a browser without installing anything.
