INvent

Build, Solve, Compete
INvent is a physics-based marble puzzle game where creativity, logic, and experimentation are the keys to success. Rotate, plan, and engineer your way through challenging marble runs as you uncover the secrets of a mysterious world.
Single Player: A Journey Through 10 Worlds
Follow a story-driven adventure across 10 unique worlds, each containing 4 handcrafted levels with new mechanics and challenges.
Every level presents a carefully designed marble track. The board is already built — your task is to analyze the path, rotate the pieces, and discover the perfect solution to guide your marble into the vent.
Master new mechanics, overcome increasingly complex puzzles, and uncover the story hidden throughout your journey.
Multiplayer: Create, Challenge, and Outsmart
Challenge another player in a competitive marble-building battle.
Each match begins with a card draft. Choose from different cards, including:
Blocks that shape the path

Add-ons that change how your level works

Power-ups that give you new strategic options

Choose four cards for yourself, while the remaining cards are sent to your opponent. Use your cards to build a custom marble challenge, then race against the clock to solve your own creation.
Once both players finish building and solving, the real challenge begins: play your opponent's level while they play yours. The first player to complete their opponent's marble run wins.
After each match, watch replays of your opponent's solution and discover how they conquered your creation.
