GridBloc™ is a brain-bending turn-based strategy game that pits runner against blocker, brother against sister, you against them all!
The runner zips around the game board collecting points while the blocker tries to GridBloc the runner by putting up walls. High score wins after two rounds.

Here's how you can help: play real games, then hit REVIEW and rate the moves. Those ratings teach us which moves are brilliant and which are blunders.

Every rated game provides the data for a GridBloc AI.

Later, anyone will be able to build and enter their own GridBloc AI — and we'll pit them against each other.

The runner starts anywhere and scores one point per new tile, moving in 8 directions, unless blocked by a wall. The blocker strategically traps the runner by placing walls, not too close not too far.
 

When the runner is blocked from new tiles, the round ends. Swap roles for round 2. Highest run total wins! (Learn about Advanced play)
