Learn the Cards

Trapweaver is a tactical dungeon-builder where every turn is a puzzle. You draft and place Rooms, Traps, Entities, and Relics onto a 3x3 grid, weaving their keywords into synergies to squeeze out every possible point.

Each card has a base value and a scoring rule. Clever adjacency, matching suits, overlapping keywords, and avoiding anti-synergies turns a modest layout into a high-scoring engine. Study the cards below to plan combos before you dive into your next run.
