Corvathane is for adults. Are you 18 or older?
Every game here is free and runs on sparks. Sparks cannot be bought, sold or exchanged, and there are no prizes of monetary value.
This browser remembers your answer, so the question appears once.
Sorry, Corvathane is closed to under-18s
The games on this site are for adults only. If gambling or gaming is worrying you or someone close to you, GamCare runs a free, confidential helpline on 0808 8020 133, open day and night.
This corner of Corvathane has nothing to do with sparks. It is a short, opinionated guide to ordinary games that run in a browser tab: chess, word puzzles, a falling-sand toy, a singing experiment and a couple of party games. We play them, write about them and link to the official sites. Nothing here is embedded, sold or sponsored.
Free, open-source chess run as a non-profit. Play the computer, a friend by link or someone at your level, or work through puzzles a few minutes at a time.
A box of pixels that behave like sand, water, fire, plants, ice and more. Paint them in, watch them react, and share or browse other people's creations.
A playful music experiment: four voices, trained on real opera singers, that harmonise as you drag them up, down, forwards and back. Record a short piece and share it.
Combine the four classic elements to discover new items, then combine those. Hundreds of discoveries, from mud and steam to sandwiches and space stations.
Like a crafting game with no ceiling. Start with water, fire, wind and earth, and combine them into new things that a language model invents as you go.
Good evenings with games usually have an end in sight. Pick tonight's time and how long one sitting takes, and the planner suggests where to stop. It runs on this page only and saves nothing.
Choose one game for the evening rather than hopping between tabs.
Decide the stopping point before you start: a number of games, a puzzle count or a time.
Keep screens off for the last hour before sleep.
Party games are better with friends you know than with strangers in public rooms.
How we choose
Every game on this page runs in an ordinary web browser, can be tried without paying and comes from its own official website. We favour games with a natural end to a sitting, a calm pace, or something you can share with people you know.
We are not paid by any publisher, we do not use affiliate links and we do not embed the games here: each card links to the maker's own site, which opens in a new tab. Names and trademarks belong to their owners, and the pictures on this page are our own illustrations, not the games' artwork. Facts were checked against the official sites in November 2026; prices, adverts and platforms can change, so the official page is always the place to confirm.
If you make a browser game you think belongs here, or spot something out of date, write to hello@corvathane.com.
Step away for a while
Pick how long the games stay locked on this device. The rest of the site stays open.
A lock of an hour or more cannot be lifted early on this browser. More tools are on Responsible Play.
