Connect the dots and find the shortest route! But beware, the world wraps in both directions. Wisely move the screen to solve the puzzle. Stuck? Use hints to highlight the correct parts of your best attempt. A hint remains active until you improve your best route. Win hints by completing puzzles or buy them directly in the in-app shop. For each level, from 3 to 35 points, complete puzzles A to Z to unlock the random puzzle and thus extend your experience indefinitely. Note that the puzzles are defined by the proportions of the screen: thus they can vary depending on the device. P=NP is a free-to-play game and contains ads. It is possible to remove ads with an in-app purchase. Other in-app purchases enable you to get additional hints. Payment functionality can be disabled in the settings of your device.

Verdict
The clearest difference is ads: Combinations at none against P=NP's shown. Combinations also leads on update cadence (every 2 months vs every 28 months) and ratings volume (39 vs 3). P=NP's advantage is rating (5.0 vs 4.6). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Combinations sells 1 one-off in-app purchase and P=NP sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
P=NP holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Combinations has 39 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 98% of Combinations's written reviews are positive against 100% of P=NP's.
Combinations ships an update every 2 months, P=NP every 28 months. The most recent releases landed on September 19, 2026 and June 2, 2026 respectively.
