About
OverviewBuild A Barrier! is a two-player board game where up to 22 people can be in one room at a time. You shrink to half your size, step onto the board, and race to reach the far side before your opponent does — all while dropping walls to slow them down and keeping yourself from getting boxed in.

How a match works
Summary
When you step onto the board, your character shrinks to half its normal size. From there, both players race across the arena to reach the other side. You can drop walls anywhere along the way to trap your opponent, force them to change direction, or slow them down — but one badly placed wall can close off your own path just as easily.
- Goal reach the far side of the arena before your opponent does
- Walls drop them to block, redirect, or delay your opponent
- Losing condition let your opponent wall you in completely
- Room size up to 22 players can be in one server at a time

Common wall mistakes to avoid
WarnEvery wall you drop changes the board for both players, not just your opponent.
Getting the most out of walls
TipsForcing a long detour is more reliable than attempting a full block. The moment your opponent has to turn around, you gain ground on the race to the far side.
- Narrow your opponent's options to one direction before you commit a wall — it makes the drop much harder to escape
- Forcing a detour is a more practical goal than a complete surround
- When your opponent has to change direction, use that moment to sprint ahead and extend your lead
- Treat walls as tools for both attack and defense — they protect your path just as much as they disrupt theirs
Wins, badges, and unlocks
