The wall, explained

Every spot on Earth is one brick. Four words. Stretcher-bond pattern, just like a real wall. 4.6 trillion bricks at about a 10-metre square. About 9% of bricks spit out a tradie roast instead of random words — that's "Roast Mode".

Free, mostly

Finding bricks, looking up bricks, saving spots, planting yer flag — all free. The only paid bit is a business sponsoring a brick: £1.19/year per brick to slap yer logo and website on it. That's it. No ads, no subscriptions, no upsells.

First come, first claimed

First person to plant their flag on a brick goes down in tradey history as the discoverer. Stays there forever unless they delete their account.
