OPTIEN

Sixteen numbers. One target. How few moves do you need? OPTIEN is a number puzzle where you drag paths across the board. Every chain you make adds to your total — and you need to land exactly on the target. Not over, not under. Exactly. Sounds simple. It is, for the first few boards. THREE STARS FOR THE SHORTEST PATH Every board is solvable, and we know the shortest solution to each one. Get close to it and you earn three stars. Take longer and you still clear the board — but you know it could have been better. That's the part that makes you start again. THREE DIFFICULTY LEVELS Easy to find your footing. Normal once it clicks. Hard for players who'd rather think ahead than try things out. NO TIMER, NO LIVES Nothing is counting down and you lose nothing by undoing a move. Think as long as you like. Play one board in a queue or half an hour on the sofa. NO FUSS No account, no sign-in, no internet needed. Open it and play. Available in seven languages: Dutch, English, German, French, Spanish, Italian and Portuguese. Ads can be removed with a single one-time purchase. Everything else is free and there are no other in-app purchases. Made in the Netherlands by Tileplay.
