Numina: Cipher Slot

Numina Slot is an offline number-strategy game where every move begins at the slot. Pull the Codex Engine lever, watch the digit and glyph slots align, then decide where to place the result across two independent puzzle disciplines.

BOARD - Place digits, clear lines. Work a 5x5 grid under numeric constraints: Sum of 7, Run of 7, Factor Chain, and Triple 7. Pre-placed digits shape each chapter's puzzle. Clear enough lines to advance. Land three 7s in a row to trigger a Cascade finisher.

CIPHER - Fill the slots, crack the code. Seven locked slots hide a secret digit sequence. Commit your guess into each slot and receive feedback chips (Higher, Lower, Parity Match, Sum Match, or Anchor) that narrow the possibilities. A limited digit Bank forces careful resource management. Fill three adjacent slots with 7 to trigger Resonance.

CODEX ENGINE - Spin the slots, stamp your tile. An ancient brass press with spinning digit and glyph slots powers both disciplines. Each pull aligns the slots into a unique tile. Glyphs modify placement: Anchor locks a digit in place, Mirror duplicates symmetrically, Echo repeats the previous effect.
