Frequently asked

What's the best building game for a 6 - 12 year old?
For young builders, short rounds beat long instructions. Fast Brix! runs a 5-minute timer on a silly 3-word prompt (like 'Penguin · Eating · Tacos') and uses whatever bricks are already on the floor. That's a whole game and it fits ages 6+.
Is there a building game that isn't on a screen?
Yes — Fast Brix! is physical. The phone only runs the prompt and the timer; the building happens with real LEGO on the floor or table. It's the fastest way to turn a brick bin into a game.
Do we need a specific LEGO set?
No. Fast Brix! is designed for the random brick bin every family already has — Classic pieces, leftover sets, even Duplo. The constraint is part of the fun.
Is Fast Brix! free?
Yes. Free on the App Store and Google Play. No ads, no accounts required to play.
How many players?
1 to 6, or even more! Solo works — the prompt gives kids somewhere to start. Family rounds are the sweet spot.

The bricks are already on the floor.
