Reach the far side. Blue starts at the top and races to the bottom row.
Red
starts at the bottom and races to the top row.
On your turn, either step your ball one cell, or place one wall on the
grid
— never both.
Walls block movement. Tap the horizontal or vertical wall icon, then tap a
spot on the grid to drop a two-cell wall. Walls can't fully seal off either player's path.
Boxed in? If the opponent's ball is directly in your path, hop straight
over it — or hop sideways if a wall is behind them.
Win the game by being the first ball to reach the opposite edge — with
only
7 walls each, every placement counts.
