Rock Slide is a rolling boulder game. You pull a rock back on a giant slingshot, let it fly down a long hillside and steer it through fences, trees, barns and fleeing tourists. Anything smaller than your rock breaks without slowing it down, and every smash feeds the rock until it grows right in the middle of the run. Hit something too big head-on and the run is over; spend the coins on a stronger sling, a bigger rock and more income, then go again and roll a little further. Cross the finish line to open the next track. If you liked Just a Rock or the Katamari games, this one is for you.
Just a Rock is one of this autumn's quiet mobile hits: a slingshot, a boulder and a valley full of things to flatten. It sits in a line of games that goes back to Katamari Damacy, where a ball rolls up everything smaller than itself, and to Rock of Ages and Giant Boulder of Death, where the boulder itself is the weapon. Rock Slide is crokocat's own take on that loop, made for the browser: instant start, no install, progress saved on your device.
Each stage is one long track down a hill, and you will not reach the end on the first try. A run lasts until the rock stops, meets something it cannot break straight on, or sinks in a pool. Every run pays coins for the metres you rolled and for what you smashed on the way, and a glowing line on the ground marks your best distance so far. The track is built in layers: soft, dense starts where the rock gathers speed and size, uphill stretches that test how far it keeps rolling, narrow passes and rows of fences or rocks that only a big enough boulder can break through.
Three upgrades share the coins. Sling makes the launch faster, Rock makes the boulder bigger, smoother and less draggy, and Income multiplies every payout. Each fifth purchase of Sling or Rock is a milestone: the rock changes its material, climbing from field stone and sandstone through coal, copper and iron to silver, gold and gems, and on later stages to obsidian, magma, lava and finally a fireball. Inside a run the rock also levels up from what it destroys, so a good line through a field of small things can turn a pebble into a boulder that flattens a barn.
Clearing a stage doubles your income for good, and you start the next track with a fresh rock and sling on a new landscape: green meadows, a snowy valley, a desert with palms and temples, and a jungle volcano with lava pools. After the fourth landscape the tracks come round again, longer and with steeper prices, so there is always a further finish line to roll for.
Small extras keep runs lively. The meteor sets the rock on fire for a couple of seconds and lets it break anything in its path; a charge comes back for free every third run, and a short video refills it when you want one right away. Tourists stand along the track and run when they see a rock coming, water and lava slow the rock down and swallow a small one, and a short video on the result card doubles the coins of a good run.
How to play Rock Slide
Roll your rock to the finish line:
- Pull the rock back on the slingshot and let go — the further you pull, the faster it flies.
- Drag left and right to steer around things that are too big and through things you can smash.
- Smashing fills the level bar above the screen; each level makes the rock bigger and faster for the rest of the run.
- When the run ends, spend coins on Sling, Rock and Income, then launch again.
- Cross the finish line to clear the stage and open the next landscape.
Game modes
| Mode | What changes | Who it's for |
|---|---|---|
| Stages | Four landscapes, then the tracks repeat longer and with steeper prices; income doubles after every finish, and the rock and sling start over on each new track. | Anyone who likes smashing things and a calm upgrade loop with a clear goal at the end of the hill. |
Tips for Rock Slide
- Steer through fields of small things: every smash grows the rock and keeps it fast.
- A glancing hit only slows you down; a head-on hit into something bigger ends the run.
- Uphill stretches stop a slow rock — a stronger sling carries you over them.
- Rows of fences and rocks across the track are gates: they open once your rock is big enough.
- Save the meteor for the gate or the barn you cannot break yet.
- Income pays off on every run that follows, and it stays when the stage changes.
Who made Rock Slide?

Frequently asked questions
Is Rock Slide free to play?
Yes. Rock Slide is free on crokocat with no download and no sign-up. It runs in your browser on desktop, phone and tablet, and your progress is saved in the browser.
Is Rock Slide like Just a Rock?
It plays on the same idea: a slingshot, a boulder rolling down a hill and everything smaller breaking in its way. Rock Slide is crokocat's own game with its own tracks, landscapes, rock materials and upgrades.
Is it like Katamari?
In one way: whatever is smaller than your rock breaks and makes it grow during the run. There is no sticking and no free roaming here — it is one long downhill track you try to finish.
Why did my run end?
The rock stopped on an uphill stretch, sank in a pool, or hit something bigger than itself head-on. A glancing hit only slows it down.
What do the upgrades do?
Sling makes the launch faster, Rock makes the boulder bigger and lets it roll further, and Income multiplies the coins of every run. Every fifth Sling or Rock purchase is a milestone with a new look.
What happens at the finish line?
The stage is cleared, your income doubles for good, and the next track opens on a new landscape with a fresh rock and sling.
What is the meteor?
A short burst of fire that lets the rock break anything for a couple of seconds. You get a free charge every third run, or right away for a short video.
