Pile of Tiles Mahjong

Pile of Tiles Mahjong is a connect board on an unusually tight schedule. Pairs are made by linking two identical tiles along a path that turns at right angles twice or fewer, and the route may not run through a tile still in place. The Butterfly Kyodai HD grid sits one row away in the same list.

Seventeen levels are on offer, and what defines them is the time frame rather than the layout: each is deliberately narrow, so a level is decided by how fast you see a legal route, not by how clever the arrangement is. Players who take the pile slowly tend to lose to the clock while still holding an easy position. Mahjong Everyday lays the same tiles out in another silhouette.

A hint and a shuffle are provided, and on short clocks both are genuinely useful — a hint saves a search, and a shuffle rescues a pile that has locked itself. The HTML5 build covers desktop and mobile, and full screen is close to necessary at this pace, since scanning for a two-turn route is exactly the task that a small window makes slow. The same free-tile rule governs the Solitaire Farm pile.

1. Spot two identical tiles somewhere in the pile.
2. Follow the route between them and count the right-angle turns: two or fewer is legal.
3. Confirm no standing tile sits on that route, then take the pair.
4. Empty the level before its short clock expires.

• Scan in straight lines first — the fastest pairs in Pile of Tiles Mahjong are the ones needing no turn at all.
• Do not save the hint, because on a narrow clock the seconds it buys are worth more than the score it costs.
• Thin the outside so that the routes around the pile stay open.
• Shuffle the moment the pile locks rather than searching a board with nothing left in it.
