Unvention is a competitive roll-and-write game where players take part in a prestigious weekend-long invention competition. Over the course of three days—Friday through Sunday—players journal their designs, gather parts, and construct mechanisms to bring their most ambitious inventions to life.

Each player has their own competition sheet to track progress—no crafting required. All you need is a printed sheet (A4 or Letter) per player and five standard six-sided dice (5D6).

At the end of each day, players present their inventions to the judges. The earlier an invention is unveiled, the more impressive it is—but timing is everything. Will your designs capture the spotlight?

At its core, Unvention is a polyomino puzzle game, where players build the polyomino shapes themselves. There are three core game systems, all heavily interlocked towards a single goal of creating elaborate inventions:

1. Journals: Mini sudoku puzzles where players try to gather wrenches; the resource required to build mechanisms.

2. Workshops: Players gather parts here, and use wrenches to connect them together and build polyomino-shaped mechanisms.

3. Inventions: The polyomino shapes of mechanisms are used in invention patterns, giving players full control to puzzle them in for most victory points, with each invention’s unique scoring criteria.
