The turtle, the classic layout
The turtle uses all 144 tiles arranged as a wide, low body with a raised ridge along the centre, four legs sticking out at the corners and a head-and-tail at the ends. It is the default in most implementations, and it is a genuinely well-designed puzzle: plenty of entry points at the edges, a hard central core, and a long middle game as the two converge.
- The easiest tiles to start with are the four legs and the head — they stick out with both long sides clear.
- The raised centre holds the deepest stack and usually decides the game.
- The layout is tall enough in the middle that early centre mistakes are the most common way to block.
Why 144 tiles matters
The full mahjong set is 144 tiles: 136 regular tiles in four copies each, plus the eight bonus tiles. Divisible pairs all the way down. Smaller or custom layouts often drop to 108 or 72 tiles by removing whole families — commonly the bonus tiles and some winds — which makes the board faster but also changes pairing, since bonus groups are often the easiest matches available.
The common alternative shapes
| Layout | Shape and feel | Difficulty profile |
|---|---|---|
| Pyramid | Tall, symmetric stack narrowing to a point | Few entry points; the top-heavy start punishes greedy centre play |
| Fortress / castle | Broad walls with an open courtyard | Walls are easy, the enclosed core is a trap for the endgame |
| Cat / dragon | Decorative silhouettes with thin appendages | Visually fun, but thin protrusions strand tiles easily |
| Flat grids | One or two layers, no stacking | Fast and relaxed; the free-tile rule barely bites |
Decorative layouts are drawn to look like objects, and the drawing is the difficulty. A tail that is three tiles long and one tile wide has almost no freedom — every one of those tiles must be unblocked in exactly the right order.
How the layout changes your strategy
The universal rule — clear height first, protect depth — bends with the shape. On a pyramid, the width at the base is your safety net, so work the base before touching the peak. On a fortress, clear the walls early so the courtyard has outside routes. On flat grids, the game stops being about depth and becomes pure pattern scanning, which is why those layouts feel closer to Mahjong Connect than to the turtle.
Whatever the shape, the underlying rules never change — they are laid out in Mahjong Solitaire rules, and the winning habits in how to win Mahjong Solitaire apply to every board. The classic turtle is waiting on Mahjong Solitaire.
