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.
