Pythagoras Mahjong is a classic mahjong solitaire where the tiles show arithmetic instead of hieroglyphs. A free tile is removed together with a tile of the same value: 3 and √9, 6 and 12/2, 8 and 2x5-2. While you clear the board, you quietly train your mental arithmetic — addition, subtraction, multiplication, division and square roots.
Three modes:
• Relax — no timer, no limits. Play at your own pace and reshuffle the board whenever you run out of moves.
• Adventure — 100 levels of smoothly growing difficulty: different board shapes (diamond, cross, rectangle, classic pyramid), more layers and trickier expressions.
• Prodigy — the same 100 levels, but against the clock and with the hardest expressions. For those who count faster than a calculator.
Hints, board reshuffle, a tiles-left counter and a total score for every level you beat. Progress is saved automatically. A great brain workout for kids and adults alike.
How to play
The goal is to clear the whole board, down to the last tile.
Tap a free tile, then tap a second one with the same value — the pair disappears. What has to match is the result, not the label: the square root of nine pairs with a plain three, because both equal the same number.
A tile is free when nothing rests on top of it and at least one side, left or right, is open. To reach the rest, take the upper layers apart first.
When no moves are left, press Shuffle: the values are dealt again across the remaining tiles. The Hint button highlights a pair that is ready to go.
You earn points for every level you finish, and speed pays a bonus: in Adventure for a fast clear, in Prodigy for the seconds still on the clock. Your total score goes to the leaderboard. If the Prodigy timer runs out, you can extend the round and finish the level.
