Support Gloopico
Buy the slimes a treat.
Gloopico is free and made by one person. If the slimes keep you company while you work, a little treat keeps them bouncing. As a thank-you, you get a coupon for supporter-only items.
SupportWhat you get
Supporter-only items
Special, carefully made accessories just for supporters — you can’t get them any other way.
More on the way
New supporter items keep coming, and your coupon opens them as they arrive.
Up to 3 computers
One coupon works on up to three of your devices, Windows or Mac.
Keeps Gloopico going
Treats turn into new slimes, items and features — and keep the app free for everyone.
Pick a treat jar
Give any amount through Ko-fi or Buy Me a Coffee and your coupon arrives by email within a few minutes (for a monthly treat, with the first payment).

That’s it
The supporter items unlock right away and stay unlocked, even offline.
Upper or lower case, dashes or spaces — all fine.
Redeeming sends only the code, a random device ID, your OS, app version and language — never your name, email or chats.
