Quantris
A Tetris-inspired puzzle game where falling pieces exist in quantum superposition. Blocks can be "quantum" (partially existing) and entangled with each other.
Overview
Pieces have a quantum "existence" property. When quantum interventions are activated, pieces enter superposition and may entangle into groups. Line clearing measures quantum pieces. Those that collapse to "doesn't exist" leave gaps, creating uncertainty in what would otherwise be a complete line.
Key mechanics
| Mechanism | Call | Game effect |
|---|---|---|
| Existence state | flip() | Set piece existence to true when spawned |
| Superposition | superpose() (alias for hadamard) | Quantum intervention puts pieces in superposition |
| Entanglement groups | iSwap(other, 0.5) | Overlapping pieces entangle into correlated groups |
| Coherence visualization | densityMatrix(a, b) | Glow intensity from off-diagonal magnitude |
| Line clear measurement | measure(...pieces) | Clearing a line collapses all quantum pieces in it |
Entanglement groups create a scoring mechanic: more entangled pieces in a clear gives a higher multiplier. The reduced density matrix drives piece visualization: probability controls opacity, coherence controls glow intensity.
