Can you make exactly 4 liters with only a 3-liter and a 5-liter cup?
BRIM is a calm logic puzzle about measuring water. Fill cups at the faucet, pour from one to another, tip water into the sink, and find the shortest way to hit the target amount. No measuring marks to help you, only the size of each cup and your own thinking.
It starts with the classic water jug riddle and keeps finding new ways to twist it.
FEATURES
• 100 hand-made stages in 10 blocks, from a gentle warm-up to real head-scratchers
• New ideas as you go: cups without a faucet, cups you can't empty, plugs, ice, stones and more
• Goals that change the game: fill two cups at once, or share out water that's already poured
• Three stars for solving in the fewest moves; replay any stage to perfect it
• Hints and undo when you're stuck, but never a solution you didn't earn
• No timers and no move limits: think at your own pace
• Kitchen styles to collect, including a Japanese tea set
• Plays offline, in 9 languages
FREE TO PLAY
BRIM is free, with optional item packs and a style for sale. Rewarded ads are optional too: watch one only if you want an extra life.
If you like logic puzzles, math riddles or quiet brain teasers, pour yourself a cup and start measuring.
