Before you write
It helps us if you include your phone or tablet model, its software version (for example Android 15 or iOS 26) and what happened just before the problem. Please don't send your child's name or other personal details. We don't need them.
Quick fixes
There's no sound
Check the phone isn't on silent and the volume is up. Then open the parent area and check the Voice, Sounds and Music sliders under Sound.
The dinos are asleep and won't wake up
That's the play-time limit doing its job. Open the parent area (hold the lock in the top-left corner for two seconds) and tap Wake up. You can change the limit under Play time.
My child keeps leaving the game
Use app pinning on Android or Guided Access on iPhone and iPad. Here's how, step by step.
I can't get into the parent area
Hold the small lock in the top-left corner for a full two seconds, then answer the sum, which is written in words, with the number buttons.
A game feels too easy or too hard
Give it a couple of play sessions; levels adjust as your child plays. To choose yourself, open the parent area and pick a stage under Stage. Pick Auto to hand it back to the game.
We got a new phone and the progress is gone
Progress is saved on the phone only. Here's what can and can't come across.
