Quick guide

How to play

Build a three-beat plan, check your colored trajectory, then commit. Enemy responses stay hidden until every entity resolves together on each beat.

  1. Draw and choose.Your four-card hand comes from a shuffled deck. Used cards discard, then reshuffle when the draw pile empties.
  2. Program three beats.Commit fewer than three cards and the empty beats become Wait. Enemies still act on all three beats.
  3. Plan for uncertainty.Attacks may target predicted empty cells. If a card is interrupted or misses, every later player card becomes Wait.
  4. Resolve together.Player and enemy actions are simultaneous. Movers choosing the same tile collide and remain in place.
