Blending · Tile Builder

Choose a terrain and paint the canvas.

Tile palette

Singles float over the canvas; every double and both triples are below. Placement finds a matching rotation.

Game rules are on hold. Explore the tiles.

How it works

Left-click places the selected tile. Empty triangle: layer 1. Occupied triangle: directly on top, layer 2. Any tile works on either layer.
Layer 2: the tile underneath must have a neighboring tile across all three edges. Fill any empty edges before stacking, even with a single.
Matching: doubles, triples, and every layer-2 tile match the visible terrain across each shared edge. Empty edges are allowed on layer 1, where rough singles can meet any terrain. The covered tile can be any terrain.
Right-click a tile to turn its terrain to the next matching rotation within its triangle. Only the visible tile turns. A single looks the same in every rotation.
Auto blend (A) refines an occupied triangle onto layer 2 with a mixed tile that fits. It never expands layer 1. Pick a specific double or triple from the palette to place mixed tiles on layer 1.
Erase (X) removes the visible tile and reveals the layer below. Undo and Redo include placement, rotation, and erasing.
Edges (D) lightly colors each tile edge by its terrain. Pink dashed seams flag a blend that no longer matches after an edit. Only two exposed layer-1 singles may mismatch without a warning.
Scroll to zoom. Right-drag or middle-drag to pan. Left-drag paints each triangle once. On a phone: tap or drag with one finger to paint; two fingers pan and pinch to zoom. The menu opens the full tile palette and canvas options. Fit resets the canvas view; zoom in to pan farther.
