Fence Builder
Fence Builder is a frantic claim-the-map duel. Move your cursor across a 20-by-10 board and stamp cells in your color. Opponents can overwrite your paint, so holding ground matters as much as rushing empty space. When the 60-second timer hits zero, the bigger territory wins.

About this game
Player 1 moves with WASD and paints with F; Player 2 moves with arrows and paints with L. Each paint press claims the cell under your cursor. Draws happen if the counts tie. Press R anytime for a fresh minute on the same grid.

Common use cases
- Settle who gets the better half of the couch with a one-minute paint war.
- Practice cutting paths that block your rival from big empty clusters.
- Play a short two-player browser match that rewards map awareness over aim.
Tips
- Paint while moving in short bursts so you leave fewer unclaimed gaps behind you.
- Overwrite a dense enemy patch near the end instead of chasing distant empty cells.
- Split focus — claim open corners early, then contest the crowded center.
FAQ
How long is a Fence Builder round?
Each round lasts 60 seconds. When time runs out, the player with more painted cells wins.
Can I take over my opponent’s cells?
Yes. Painting a cell sets it to your color, so you can overwrite territory the other player already claimed.
What if both players have the same count?
The match ends in a draw when the cell totals are equal.
Do we need two devices?
No. Both cursors run on one keyboard in the same browser window.
