Rock Sitter is a free browser game where you babysit a virtual pet rock named Gerald. Most of the time nothing happens, but random events appear the longer you stay, from snails and rain to ultra-rare surprises.

Yes. It runs in any web browser with no download, account, or sign-up.

Doris is a second rock who moves in once you complete the main Rock Log. She tries on collectible looks, including seasonal ones that are only available in certain months.

Q: Does my progress save?

Yes. Your Rock Log, sitting time, streak, and Doris's Closet are saved in your browser on your device. Clearing your browser data resets them.

Q: How do I find rare events?

Keep the page open. Events roll every few seconds while you watch, rarer ones are less likely, and some only happen at certain times, on certain dates, or after visiting several days in a row.

You're babysitting a rock. Watch it. Things happen if you stay. Leaving is noticed.

The rock is here. You are here. That's the whole thing, for now.

Rock Log

Everything you've seen happen to the rock. Some things only happen if you stay long enough, and some only on certain days. Calendar, streak, and grail entries are bonus finds.

Put your brand next to Gerald

Sponsor a rock event for a week. Your emoji, a line of text, and a link, shown to everyone sitting with Gerald. It also becomes a limited-edition find in the Rock Log.

What is this?

Rock Sitter is a very small website where you watch a rock. Most of the time the rock does nothing, which is what rocks are best at. Every so often, something happens: a snail passes, a bird sits down, it rains. Some events are rare. A few are legendary. Some are secrets, and the log won't tell you how to find them.

Your Rock Log saves what you've found on this device, so you can come back and keep collecting. Stay long enough and the rock starts to warm up to you. If you switch tabs, the rock notices, and the timer waits for you.

Tap the rock to pat it. It allows this, within reason. Finish the main log and someone new moves in. Some things only happen on certain days, and one thing almost never happens at all.

Questions

Is Rock Sitter free?

Yes. It runs in any web browser on phone or computer, with no download, account, or sign-up.

Does my progress save?

Your Rock Log, sitting time, daily streak, and Doris's Closet are saved in your browser on this device. Clearing your browser data resets them.

How do I find rare events?

Keep the page open. A new event can happen every few seconds while you watch. Rare, legendary, and ultra-rare events each happen at most once a day. Some events only happen at certain times of day, on certain dates, or after you visit several days in a row, and one is a 1 in 10,000 chance.

Who is Doris?

Doris is a second rock who moves in once you finish the main Rock Log. Every 10 minutes she tries on a new look. Some looks are mythic, and seasonal looks are only available in their month.

Why does the timer stop when I switch tabs?

Because the rock only counts time you actually spend with it. It also notices when you leave.
