Why Sagax?

We believe a few focused minutes a day can make a difference. So we build games that are calm, polished and respectful of your time and your privacy.

Inspired by cognitive science

Each game targets a specific skill — sequential, visual-spatial, recognition and working memory, planning, spatial reasoning and logical deduction.

Short sessions, real progress

Levels grow with you. Start easy, then climb as high as you can in just a few minutes a day.

Calm, polished design

A sleek dark interface, ambient music and tactile sound effects. No clutter, no pressure.

Privacy first

No accounts, no sign-up, no personal data. Only anonymous statistics that help us improve the games.

Free, with no ads

No adverts, no in-app purchases, no paywalls. Just download and play.

Made for everyone

Available in English, Portuguese, Spanish, French and German, with a native experience on Android and iOS.
