Capitol Dome — Mahjong Solitaire Layout
Free Online Mahjong Solitaire Game
Play Mahjong Solitaire online on TheMahjong.com, try fullscreen mode, and use other helpful features. We offer more than 260 Mahjong Solitaire layouts, all available for free.
Layout Description
“Capitol Dome” recreates the silhouette of the U.S. Capitol dome — the seat of the U.S. Congress located on Capitol Hill in Washington, D.C. The layout was inspired by the second version of the dome, completed in January 1866 and still standing today. This is one of the themed layouts created in celebration of U.S. Independence Day.
“Capitol Dome” is built from three tile layers, mostly concentrated at the base. The shape loosely mirrors the dome’s vaulted design. Its recognizable appearance is enhanced by the central tiers and columns. Due to its structure, the layout offers a large number of open tiles at the beginning, allowing for a variety of strategic approaches. The main challenge lies in the long horizontal rows forming the base tiers.
Gameplay Tips
- Focus on the tiers: These long horizontal rows block access to many tiles. Clearing them should be a top priority.
- Watch the layers: Although most tiles are spread across one or two layers (with up to three at the base), this layout does not make clearing easy. The tiers often obstruct access, so careful, step-by-step removal is essential.
- Do not ignore the top: The upper part of the dome may seem simple, but during the mid-game, it can cause dead ends if key tiles become blocked.
- Use reshuffle if needed: If you run out of moves, do not hesitate to use the shuffle function. It can help you finish the level and discover new paths to victory.
Difficulty: 3 out of 5.
With its three-layer structure, defined geometry, and many early moves, “Capitol Dome” is moderately challenging. However, even experienced players may encounter unexpected blocks — especially if they overlook the key tiers.
About Mahjong Solitaire on TheMahjong.com
Mahjong Solitaire is a tile-matching puzzle game that uses traditional mahjong tiles, but it is played very differently from classic four-player mahjong. Instead of building a winning hand against other players, your goal is to remove matching open pairs and clear the board.
TheMahjong.com offers more than 260 Mahjong Solitaire layouts, including Turtle, Fish, Butterfly, and many others. The basic rules stay the same, but each layout changes the shape of the board, which tiles open first, and how much planning the game needs.
Whether you are new to Mahjong Solitaire or already know the rules, you can choose a layout, play at your own pace, use helpful features such as hints and shuffle, and enjoy the game online for free.
How to Play Mahjong Solitaire
Remove tiles that are not blocked.
You can remove a tile only if it is not covered by another tile and has either its left or right side free. If a tile is blocked on both sides or covered from above, it cannot be removed.
Choose pairs carefully.
Each regular tile appears four times on the board. This means you may have more than one possible match, so choose the pair that helps open the board.
Season and Flower tiles do not need identical pictures.
There is only one of each Season and Flower tile, but they still form matching pairs. Any Season tile can match another Season tile, and any Flower tile can match another Flower tile.

Mahjong Solitaire Tips and Tricks
Look at the layout before your first move.
Before making your first move in Mahjong Solitaire, take a moment to look over the board. You may spot a move that opens an important part of the layout. Pay attention to Season and Flower tiles too: they do not need identical pictures to form a pair.
Choose moves that uncover more tiles.
Try to match pairs that reveal new tiles or open blocked parts of the board. Some pairs do not create any new options, so it may be better to leave them for later.
If you see three matching tiles, think before choosing.
When three identical tiles can be removed, choose the pair that opens more of the board. Sometimes it is better to free the fourth tile first, so you can remove both pairs safely.
If all four matching tiles are available, remove them.
When all four identical tiles can be removed, you can usually match both pairs right away. This clears space without leaving an unmatched tile behind.
Start with the ends of long rows.
Tiles in the middle of a long horizontal row are often blocked on both sides. Remove matching tiles from the left and right ends of the row to shorten it and make more tiles available.
Pay attention to tall stacks.
Tall stacks can hide important tiles underneath. They can also contain matching tiles placed on top of each other, which may block progress if no other matching tile is available.
Use Hint and Undo when needed.
If you get stuck, use Hint to find an available move or Undo to try a different choice. These tools are especially useful when a move looks good at first but does not help open the board.
