Acumen
Acumen is nine small brain games in one place, and a new set every day. Missing Link asks you to find what three words secretly have in common. Alibi gives you nine words and one culprit. Bluff hands you three facts about a topic and dares you to spot the one that’s made up.
The rest rotate through memory, codebreaking, speed sorting, and pattern logic, so no two days feel the same. None of them take more than a minute or two, which was the point. I wanted something I could actually finish during a coffee break instead of one more app that asks for an hour.
It’s free, it resets daily, and it’s the kind of thing I check first thing in the morning now.
