GOAL
Guide the sphere from the central fountain into your study room entrance (gold ring on your edge).

GAME SETUP
The sphere starts on the fountain at the board's center. The board is empty — build plates and walls to steer the sphere toward your entrance.

YOUR TURN

• Lay Plate: Click any empty cell to place a walkable Plate. If placed adjacent (up/down/left/right) to the sphere, the sphere rolls onto it and continues sliding through any connected plates!
• Lay Wall: Click any empty grid-gap line to place a Wall. Walls block the sphere's movement.
• Push Wall: Click your own wall to select it, then click an adjacent gap to push it. Connected walls slide together.
• Topple Wall: Click your wall to select it. Click an adjacent cell to topple it — the wall becomes a walkable plate!
• Push Sphere: Select the sphere, then click a direction arrow to push it. It slides in a straight line through connected plates until blocked. If it stops on your entrance — you win!

VARIANT — OPEN ENDS
The sphere only stops at walls. If it rolls past the end of a plate road or over the board edge, it falls and returns to the fountain. Your own entrance is a doorway — the sphere rolling into it wins immediately, no wall needed.
