CratePals
A crate lab for ages 6–8: open a crate whose chances are printed right on the lid, watch your pile grow toward those odds, and see how rarely the rare prize really comes. Then make your own crate and guess the odds. Opens are free forever — nothing to buy, nothing runs out. On-device; nothing leaves your device.

Meet the cast
CratePals has a tiny friendly crew who make chance honest: Cratey the hamster shows a crate's odds right on the lid, Oddo the owl reads how likely each prize is before you open, Pipkin the mouse's growing pile drifts toward those odds the more you open, and Rara the magpie learns that rare means seldom - not better. Each friend shows ONE gentle idea about chance; everything is spoken, and there is no way to lose.
Cratey
Honest odds on the lid - Cratey the hamster, the stall-keeper whose every crate shows its chances painted plainly on the top, out in the open, so you always know before you open

Oddo
Read the chance first - Oddo the owl, who reads how likely each prize is before you open: lots of dots means likely, a lonely dot means it hardly ever comes
Read chapter →
Pipkin
The pile finds the odds - Pipkin the mouse, whose growing sorted pile starts jumbled but, the more you open, settles to match the chances on the lid (the law of large numbers)
Read chapter →
Rara
Rare means seldom, not better - Rara the magpie, who chases the shiny 'rare' crate, learns it comes only once in a long while, and that the sure everyday prize is just as good
