Frequently asked questions
+Are these brain games actually free?
Yes. The whole solo arcade is free to play. Plus ($9.99/mo) adds skill tracking over time, the IQ Test + Brain Profile, premium games, and removes ads.
+How long does each game take?
Most are 1–3 minutes — built for a coffee break or a commute. The Daily Challenge is a fixed set that runs about 5–7 minutes.
+Do I need an account to play?
No. You can play any free game without signing in. An account lets you save scores, see your progress, and unlock the daily streak counter.
+Will brain games actually make me smarter?
Honest answer: brain games train specific skills the games target — number recall, mental math speed, pattern detection. They won't change your underlying IQ, but they reliably improve the cognitive dimension being trained.
+What's the Daily Challenge?
A new set of brain games posted every day. Same set for everyone, so you can compare your score against the global leaderboard. Streaks reward consistency — 7-day, 30-day and 100-day badges live in your profile.
+What makes Plus worth it for solo players?
Three things most regular players want: skill-tracking dashboards, the full IQ Test + Brain Profile, and ad-free quick games. If you play more than once a week, Plus pays back fast.
