Are you a fast thinker? Check it out and learn to take the right decisions fast, as balls of different colour will be rushing from one side of the screen to the other and you have only one chance to drop it in the right place before the ball falls. Collect at least three balls of the same colour in vertical or horizontal position to make them disappear. Use bombs to demolish towers and try not to miss, or else it will ruin your plans. Sounds too easy? Try playing on a higher level. Good luck ;)

So you think you understand this thing you’re holding? Think again. Stop tapping. Stop swiping. In fact, stop touching the screen at all. To crack Blackbox’s puzzles you’ll need to find solitude and stillness, climb mountains, call on friends, get in tune with the cosmos, and think outside the box. Minimalistic visual clues make for incredibly satisfying “Aha!” moments, while sonic interfaces provide an extra level of guidance and nuance that makes Blackbox accessible with or without vision. Thoughtful haptic feedback, Easter eggs on Easter eggs, and solutions that can’t be found beneath the glass of your screen redefine what a puzzle can be. You’ll never see your device the same way again. Think you’re clever? Prove it. (Blackbox is a living game under active development by Ryan McLeod. When not eating burritos or drinking coffee, he’s busy designing and developing new Blackbox challenges.) ■

Verdict
The clearest difference is review sentiment: Blackbox at 93% against 1 Chance's 0%. Blackbox also leads on update cadence (every 9 days vs every 88 months) and ratings volume (110K vs 1). 1 Chance's advantage is in-app purchases (none vs 10) and rating (5.0 vs 4.8). On price, ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Blackbox sells 10 one-off in-app purchases. 1 Chance asks for nothing beyond the download.
1 Chance holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Blackbox has 110K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of 1 Chance's written reviews are positive against 93% of Blackbox's, so the app with the better star average is not the one people write more warmly about.
1 Chance ships an update every 88 months, Blackbox every 9 days. The most recent releases landed on October 31, 2026 and November 8, 2026 respectively.
