Lab Merge treats the rules and the board as separate choices. Select 2048, Threes, Fibonacci, or Powers of 3, then choose a layout. Each combination has its own saved run and best score.
Choose a rule set#
| Mode | How tiles combine | Movement and goal |
|---|---|---|
| 2048 | Equal powers of two double | Compress to the edge; reach 2048 |
| Threes | 1 + 2 = 3, then equal values from 3 upward | Move one cell; use the next-tile preview; no fixed winning tile |
| Fibonacci | Consecutive sequence values in either order; 1 + 1 = 2 | Compress to the edge; reach 2584 |
| Powers of 3 | Equal pairs advance to the next power: 3 + 3 = 9 | Compress to the edge; reach 2187 |
Choose a board shape#
Square boards use the familiar four swipe directions. The current built-in set includes five numbered layouts plus L-Shape, Ring, Diamond, and Triangle silhouettes made from square cells.
Hexagonal boards allow movement along six directions. The current built-in set includes three layouts, ranging from a compact introductory grid to much larger fields.
Triangular-cell boards also use six directions across three reversible axes. Two beta presets—one with 18 cells and one with 9—are available after enabling the home-screen beta switch. They are distinct from the Triangle silhouette preset, which is shaped like a triangle but uses square cells.
Experimental terrain#
The development build also contains example boards for features being tested:
- Ice groups cells into terrain regions.
- Portals connect exactly two matching endpoints.
- Walls block cells within the board outline.
- Void cells shape the playable boundary.
- Rocks occupy ice cells and alter the playable space.
The included experimental examples are Frozen Square, Portal Walls, and Hex Terrain. Their rules and presentation may change before release.
How progress is organised#
Changing mode or layout does not discard your other saved runs. Lab Merge records a separate active game and best score for each combination, while completed runs contribute to mode- and board-specific statistics and tile milestones.
