LEGO games you can start in the next five minutes.
No new set, no instructions, no setup. Every game here works with the mixed brick bin you already own — and most of them are over before anyone gets bored. Ages 6+.

Open →Why prompt games beat instruction sets
- They fit real evenings. A five-minute round happens on a Tuesday. A four-hour set does not.
- Nobody can lose at them. There's no picture on the box to fall short of.
- Mixed bins become an asset. The weird leftover pieces are exactly what makes a build funny.
- Everyone plays at once. Same prompt, same timer, wildly different results.
Frequently asked
- What LEGO games can you play with a random brick bin?
- Prompt games. Instead of following instructions, you get a constraint — three silly words, a time limit, a theme — and build with whatever pieces are in the bin. Fast Brix! deals the prompt and runs the timer, so a mixed bin becomes the whole game.
- Are there LEGO games that aren't video games?
- Yes. Most search results for 'LEGO games' are digital titles. Fast Brix! is a physical game — the phone only reads out the prompt and counts down five minutes while everyone builds with real bricks.
- What's a good LEGO game for a group?
- Speed rounds. Everyone gets the same three-word prompt and the same five minutes, then you go around and explain your builds. Groups of two to six work best, but a classroom of twenty works if you build in pairs.
- What age are LEGO games good for?
- Ages 6+ for prompt games. Younger builders do great with seven-minute rounds and an adult reading the prompt out loud twice.
- Is Fast Brix! free?
- Yes — free on the App Store and Google Play, with no ads.
