Making four dimensions inspectable
Tesseract extends chess movement across four axes, each with eight positions. Fixing the z and w coordinates produces an ordinary 8 × 8 board: 64 slices cover the full space of 4,096 coordinates.
Browser simulation
The React interface combines a rotating Canvas 2D projection with a plane inspector. A Web Worker runs the move engine while the interface remains available for orbiting, selecting pieces, and inspecting coordinates. Visitors can run two CPU players, advance one move at a time, or reset the simulation. Continuous playback holds each result for 3.5 seconds, then starts a fresh game while the projection keeps rotating.
Limits
The CPU checks for immediate mates and considers opponent replies for its top 12 move candidates, with a bounded search for opponent mating threats. This is an experiment in spatial interaction, not a strong chess AI or a standardized four-dimensional rule set. The demo runs entirely in the browser.
