Perilattice
A deduction game with the confidence of a great arcade cabinet: every field is solver-certified, every cascade feels physical and the five-sector score attack rewards clean proof rather than lucky guesses.
Perilattice turns deduction into a tactile arcade machine. Read numbered proof tiles, mark only fractures that logic proves, then chord satisfied clues to open whole regions in a Certainty Cascade. Learn through six authored Expedition chapters, chase a clean five-sector leaderboard record in Arcade Run, solve the shared UTC Daily Lattice, or practice on three field sizes. Every generated board is rejected unless the built-in solver can finish it without a forced guess. Keyboard, pointer and touch controls, reduced-motion and reduced-flash options, shape-backed number symbols and resilient local progress make every route playable standalone or inside ArcadeReboot.
Choose Expedition, Arcade Run, Daily Lattice or Practice, then press Start. Reveal with left click, tap or Space. Mark a proven fracture with right click, long press or F. Move keyboard focus with the arrow keys. Chord a revealed number with Enter, click or tap when its adjacent marks equal the number. Press P or Escape to pause. Expedition progress and options persist locally. Only a fresh five-sector Arcade Run is ranked; clearing a sector banks its value once, while retrying a sector preserves earlier banked progress but makes the continuation unranked. Daily Lattice is unranked and uses ArcadeReboot server UTC when available, with browser UTC fallback.
