Octagon Mahjong Solitaire
About the Octagon Layout
Octagon arranges 120 tiles into a clean eight-sided figure built from layered inner rings, like a target seen from above with straight edges instead of curves. The outer ring traces the full octagonal perimeter, and inside it sit progressively smaller octagons stacked in tiers, so the board rises toward a raised cluster at the centre. The effect is architectural and orderly, with a strong sense of concentric structure: every edge is a clean diagonal or straight run, and the symmetry around all eight sides gives it a poised, almost ceremonial look.
With 120 tiles this is one of the larger boards in the set, and at 3 out of 5 it earns its difficulty mainly through volume and the buried heart of the figure. The outermost ring is wide open and easy to nibble at, but each inner tier shields the one beneath it, so the central tiles are the last to surrender. It plays as a steady, methodical peel from the rim inward, satisfying for players who enjoy watching a large structure dissolve layer by layer rather than scrambling through chaos.

How to Clear the Octagon Layout
Attack the perimeter first. The outer octagonal ring has the most exposed left and right edges and almost nothing stacked on top of it, so it is your richest early hunting ground. Clearing it not only banks easy matches but also opens the flanks of the next ring in, which is how you create access to the interior.
Work ring by ring, but unevenly. You do not need to finish an entire tier before starting the next; instead, look for spots where peeling a few tiles off one side of a ring exposes the corners of the ring beneath. The eight corners of each inner octagon are natural weak points, because a corner tile is exposed on two outer faces at once and tends to free up earlier than a tile in the middle of a straight edge.
The crux is the raised central cluster. Those top tiers cap a small stack of tiles that stay locked until everything around and above them is gone. Keep a mental note of which centre tiles are buried deepest and try not to spend their matching partners early on the easy outer rings, or you will reach the climax of the board with a centre tile whose twin is already gone from reach.
For the endgame, aim to arrive at the centre with as many flexible tiles as possible still in play. Flowers and seasons are gold here, since any flower matches any other flower and any season any other season, giving you wildcard-style relief exactly when the tight central stack offers the fewest options. If the core does jam, Shuffle will re-deal the remaining tiles into a solvable layout.
The Story Behind the Octagon Layout
The octagon is a shape loaded with meaning across cultures. In Chinese tradition the bagua, the eight-sided arrangement of trigrams, represents the fundamental forces of the cosmos and is a classic motif in feng shui, which makes an eight-sided Mahjong board feel quietly at home with the game's heritage. The number eight is itself considered deeply auspicious, a symbol of prosperity and good fortune, so an Octagon layout carries a faint promise of luck.
Architecturally the octagon bridges the square and the circle, and builders have long used it for exactly that reason, from baptisteries to pavilions to the famous towers that needed strength on all sides. The concentric inner rings of this layout echo those tiered structures, each ring a smaller storey rising toward a central point, so dismantling the board feels a little like taking apart a small, perfectly balanced tower from the roof down.
Frequently Asked Questions
Where is the best place to start on the Octagon?
The outer ring. Its tiles are exposed on the flanks and carry nothing on top, so they offer the easiest early matches and, once cleared, open access to the next ring inward. Build from the rim toward the centre.
Why are the centre tiles so hard to reach?
The Octagon is built from layered tiers that rise toward the middle, so the central cluster is capped and shielded by every ring around it. Those tiles are designed to be the last to free up, which is why the board peels naturally from the outside in.
This is a big board. Any tip for not losing track?
Treat the eight corners of each inner ring as landmarks. Corner tiles are exposed on two faces and free up sooner than mid-edge tiles, so they make reliable footholds for opening each successive tier without you having to track all 120 tiles at once.
What should I save for the central stack?
Keep flexible tiles in reserve, especially flowers and seasons. Because any flower matches any flower and any season any season, they act as wildcards and are most valuable when the tight central tiers leave you with very few legal moves.
