01 / A little room to grow
One swipe.
Everybody moves.
A bigger shell changes everything. Line the crabs up in size order, then send the whole queue moving house.
Find a better fit.
Every crab needs a shell exactly one size bigger than the one it’s wearing.
Get the queue right.
Bring them together in size order, with an empty shell ready at the front.
Make a little room.
One swipe moves the queue. Every old shell becomes someone else’s new home.
Inspired by real hermit crab vacancy chains. One good move makes room for everyone.
02 / Six stops along the shore
A coast full of
little surprises.
Forty puzzles in every pool. New neighbours, new obstacles, and everything you’ve learnt coming along for the ride.
The Rock Pool
Where it all starts. Line them up, move them in, and mind the bottle caps and cracked shells.
Kelp Shallows
Currents carry anything that stops on them. Use them, or get swept away.
Tide Flats
Every few moves the tide floods the blue tiles, and weed-slick rock sends you sliding.
Gull Point
A gull carries off empty shells left in its lane. Crabs wearing anemones won’t stand next to anyone.
Crowded Cove
Some crabs are about to grow and will need a bigger shell again. Bruisers don’t wait their turn.
The Wreck
Barnacled shells move as one, until someone moves in. Everything you’ve learnt, all at once.
Pools 1 to 3 of 6
03 / A few pushy neighbours
Not everyone
waits their turn.
A bruiser takes the shell it wants. A smaller crab ends up without a home. And suddenly your tidy queue needs a new plan.
Growth spurts
Some crabs will need a bigger shell all over again.
Bruisers
They don’t always wait for a shell to become vacant.
Barnacled twins
Two shells move together, until someone moves in.
04 / Make a day of it
First light.
Last move.
One more try.
Every pool is a day at the beach. Five sets of eight puzzles carry you from Dawn to Dusk, with the light shifting and the challenges growing.
- Dawn
- Morning
- Midday
- Arvo
- Dusk
Eight puzzles in each set. Explore at your own pace.
05 / Think before you shuffle
No ticking clock.
Just one good plan.
Take your time, but watch your moves. Each puzzle has a move budget. Run out, and the tide comes in.
Three undos give you room to rethink. Each one returns the move you spent.
Three pearls to chase.
On every puzzle- 01Find a solution.
- 02Match par.
- 03Finish without undoing.
Earn sea glass through play and spend it on hints. Never buy it.
06 / A home for everyone
The smallest shell.
One last home.
When everyone has moved up, there’s still one shell left. Just the right size for the smallest arrival.
Nobody’s old home
has to go to waste.

shell questions.

All 40 Rock Pool puzzles are free. One purchase unlocks the other five pools and their 200 puzzles permanently. Final pricing will be shown in the store.
Is it a race against the tide?
No. There is no timer. The tide arrives when your move budget runs out, so you can take as long as you need to think before moving.
What happens if I get stuck?
You have three undos per try. Hints cost sea glass, which you earn by playing. After three tries at the same level, you’ll be offered a free hint for it.
