Think beyond the answer
A puzzle built around the path
In Signa, finding a true equation is only the beginning. The order of your moves matters, and every choice shapes what remains on the board.
Read the whole board
Trace connected tiles in the right direction. A good equation must also leave the next move possible.

Sound effects and haptics can be changed in Settings. Where required, advertising consent and privacy choices are also available in the app.

Use Restore Purchases in the shop to recover Signa Pro with the original Apple or Google Play account on the same store platform. Pro removes automatic level-break ads; optional rewarded ads remain available when you choose them for a hint.
Quick answers
Frequently asked questions
Why was my equation rejected?
A chain must follow connected tiles in sequence, use a supported expression, and satisfy the board's rule. The complete board may require a specific order even when another partial equation is mathematically true. If a valid chain appears to be rejected, send us the level number and a screenshot.
How do hints work?
A hint shows the next intended chain and its direction. You can earn or purchase additional hints in the shop. Rewarded ads may also grant one hint when available.
Will my progress sync to another device?
Signa does not currently use player accounts or cloud progress sync. Progress, settings, and hint balance are stored locally on your device and may be lost if the app is deleted.
Can I restore purchased hints?
Hint packs are consumable purchases; restore does not recreate consumed hint purchases. Unused hints have no time-based expiry while their local app data remains available. The non-consumable Pro purchase can be restored.
How do I report a problem?
Email mnpekdemir.apps@gmail.com. Please include the level number, device model, operating system and app version, and a screenshot or short screen recording when possible.
