Shards rain from the side prisms. Keep the core standing.

A falling-block stacker reimagined on a triangular lattice. The board is a magnetic tri-prism: a triangular core well with three same-sized side prisms on its edges. Angular shards built from unit triangles drop from the side prisms into the core — its solid edge is the floor, its two dashed edges are open skies. Spin the prism 120° and the floor shifts while every locked shard stays magnetically stuck, so all three edges carry stacks. EASY auto-spins the prism so every drop plays like a classic stacker; HARD hands you the rotation and launches shards through the left and right prisms at off-center angles for 1.5× score. Fill rows along any edge to shatter them, chain cascades, string clears across all three edges for a Trifecta — and don't let any edge overload. Survive 30-second waves to level up: shards fall faster and the prism snaps quicker.
