Good to know
Is Wonder Worlds really free?
The one free game on TotsName is Star Shuffle in Brainy Buddies — anyone can play it without signing in. All 20 Wonder Worlds games open with the Day Pass.
What is the Day Pass?
A Day Pass costs 10 credits and unlocks all 41 Brain Games — both Brainy Buddies and Wonder Worlds — for 24 hours from the moment you unlock. Opening a game again, refreshing or using a second tab never charges you twice while the pass is active.
What happens after 24 hours?
The paid games lock again and Star Shuffle stays free. Unlocking another day is another 10 credits — nothing renews by itself.
Which ages is it for?
Ages 4 to 12. Every game gets a little harder each level, so younger children and older ones both find a good level.
Does it need an app or an install?
No. It runs in the browser on a phone, tablet or computer. A few games use sound, so keep the volume on.
Is it safe for children?
There are no ads inside the games, no chat and no sign-up needed to play the free game. Best scores are kept only on the device you play on.
