About the game
An original browser game by Zarocer.
Turn a small board into a satisfying marble workshop. Every track tile has two openings. Rotate the pieces to connect the entrance to the exit, then launch your golden marble and watch your plan unfold. A successful route must collect all three crystals before reaching the bottom-right exit. The campaign has 24 levels, growing from 4 × 4 boards to 6 × 6 puzzles. Locked tracks provide useful anchors, while five launches per run give you room to experiment. Aim for fewer rotations and improve your local records. The shared daily challenge changes at midnight UTC. Mouse, touch and keyboard controls make it easy to build on different screens. Hints and undo help you learn; assisted and restored runs remain local. Eleven in-game languages are available, and you can play without an account.
