8Soluna features
8Soluna packs a full logic-puzzle experience into your browser: three game modes, a smart hint that teaches you, colorblind-friendly themes, dark mode and six languages — all free to start, with nothing to install.
What game modes does 8Soluna have?
8Soluna gives you three distinct ways to play, whether you want a quick daily fix or an endless challenge:
- Daily Challenge — one fresh puzzle each day, identical for every player, always free.
- Campaign — 200 stages across 20 worlds that introduce each mechanic gradually; the first 60 are free.
- Endless — unlimited puzzles at facil, medio, dificil or expert, in Classic, Against the Clock and Zen modes.
How does the hint work?
The built-in hint never just fills a cell for you — it explains which rule forces the next move, so you learn the deduction instead of guessing. If you've made a mistake, it points that out first.
Can I customize how 8Soluna looks?
Yes. 8Soluna ships with eight colorblind-friendly symbol themes — from the classic ☀️ Sun and 🌙 Moon to fruits, animals and cosmic sets — plus a light and dark mode. Some themes are free and others are part of the premium unlock.
What else makes 8Soluna comfortable to play?
- Runs in any browser on phone or desktop — add it to your home screen to play like an app.
- Every puzzle has a single solution reachable by logic alone.
- Play as a guest, or sign in to sync progress across devices.
- Available in English, Portuguese, Spanish, French, Italian and German.
