Who it's for

Fans of spatial logic puzzles like Battleship or tangram deduction who enjoy piecing together a hidden layout from indirect clues.

Not for you if…

Skip if the group dislikes abstract spatial puzzles β€” there's no theme-driven narrative here, just pure grid deduction.

🦊

Vibe's take

Cerebral and quietly tense β€” a slow build of spatial deduction punctuated by sudden urgency whenever someone thinks they've spotted the pattern first.

About this game

An asymmetric deduction game where one player secretly places tangram-shaped minerals on a hidden mine grid while everyone else fires probing waves from the edges, tracking each bounce to deduce exactly where the minerals sit.
