144 tiles, five layers, one objective
Remove all 72 pairs from the Turtle layout. The five layers contain 87, 36, 16, 4, and 1 tiles, from the bottom upward. New deals change the tile arrangement while preserving this shape. The generator searches for a deal with a removal path and falls back to a random deal if that search fails. Solvability is not guaranteed, and following a different removal order can also leave you stuck.
| Group | Number of tiles | Matching rule |
|---|---|---|
| Characters, bamboo, dots | 108: 1–9 in each suit, four of each | Same suit and number |
| Winds | 16: four each of east, south, west, north | Same direction |
| Dragons | 12: four each of red, green, white | Same dragon |
| Flowers | 4 different pictures | Any flower with any flower |
| Seasons | 4 different pictures | Any season with any season |
A bird represents one bamboo. The white dragon is the tile with a rectangular frame. The numbered flower and season pictures do not match across those two groups.
When a pair is legal
Both tiles must be open at the time of removal. A tile is open when no remaining upper-layer tile overlaps it and at least one horizontal side is free of a neighboring tile on its layer. Neither a free top edge nor a free bottom edge replaces that left-or-right requirement.
Matching tiles can be far apart and can sit on different layers. They do not need an empty connecting path. Removing one pair may reveal new tiles, free a row's side, or do both. A partly exposed tile under another tile is not yet open.
What Open Matches counts
This counter shows all legal two-tile choices on the current board. Two open copies of a symbol give one choice; three copies give three choices; four copies give six choices. Those six choices are alternatives, not six pairs you can remove from four tiles. A higher counter is useful but does not prove the whole board is still solvable.
How points are calculated
Every successful pair earns 100 base points. Two independent bonuses can increase that reward:
- Quick chain: match again within eight seconds of the previous pair. The second pair in the chain gets 45 extra points, the third gets 90, the fourth gets 135, and so on. A gap longer than eight seconds resets the quick chain.
- Same-type streak: remove consecutive pairs with the same matching key. The second pair of the same type gets 35 extra points. For example, four bamboo followed by four bamboo qualifies; four bamboo followed by six bamboo does not. Flowers count as one type, and seasons as another. This streak depends on pair order, not elapsed time.
| Move | Calculation | Running total |
|---|---|---|
| First pair: four bamboo | 100 | 100 |
| Second pair: four bamboo, 5 seconds later | 100 + 45 quick + 35 same-type | 280 |
| Third pair: east winds, 6 seconds later | 100 + 90 quick | 470 |
| Fourth pair: dots, more than 8 seconds later | 100 | 570 |
Clearing all 144 tiles adds a 5,000-point completion bonus. Time passing does not subtract points, and there is no remaining-time multiplier. A faster move is not necessarily a better move if it prevents you from clearing the board.
Hint costs and repeat presses
All hints before the first successful pair are free. Once the timer starts, the cost rises each time a new, previously uncharged physical pair is shown. Repeating the same pair never adds another charge, even if you press Hint many times.
| Charged hint | Points deducted |
|---|---|
| First | 85 |
| Second | 150 |
| Third | 235 |
| Fourth | 340 |
| Fifth | 465 |
The cost for charged hint number n is 40 + 35n + 10n². Your score stops at zero: a 150-point hint used with 100 points leaves zero, not a hidden minus 50. Your next pair earns points from zero. The count of charged hints still advances when you cannot pay the full cost.
A hint displayed before play can be charged if requested again after the first successful pair. It was free while the clock was stopped, rather than permanently exempt from later costs. Hint offers a legal pair; it does not search for an optimal solution.
Timer and end conditions
The ten-minute countdown begins with your first successful pair. It continues during play and while you look at game dialogs or another tab. There is no pause button. It stops when the round ends.
Clearing every tile wins the round. No legal pairs with tiles remaining ends it early, and the clock reaching zero ends it even if moves remain. The no-moves result appears after a short delay so the last removal can settle.
Completion is removed tiles divided by 144, rounded to a whole percentage. Removing 116 tiles leaves 28 and reports 81% complete and 19% remaining. A fully cleared board gets Congratulations; an unfinished board at 80% or more gets Good game; 60–79% gets Nice progress; below 60% gets Keep practicing.
