However, multiple reviews cite stability problems after updates, intrusive ads on a paid app, and usability irritants like small controls and unresponsive UI. Some note limited board sizes and lack of retina optimization. Overall, the core Kakuro gameplay shines when the app runs smoothly, but reliability and monetization changes detract from the experience. ### Pros - Well-generated, genuinely challenging Kakuro puzzles with solving tools that aid without gimmicks - User-friendly layout and UI, plus an excellent dark mode - Clean, non-gamified experience focused on Kakuro rather than coins or celebrations - Strong, addictive Kakuro gameplay that stands out among apps - Long-standing app with solid features like scorekeeping and configurable options ### Cons - Ads appear in a paid app and some users report being asked to pay again or encountering intrusive IAP/ads - Stability and compatibility issues across updates (crashes, tries to load, not working on various iOS versions) - UI/input problems after updates (tiny touch targets, buttons too small or hard to hit, slider/timer issues) - Lack of retina optimization on older devices - Limited puzzle board sizes and progression/ unlocks can frustrate experienced players ## Similar extensions and apps - [Kakuro: Classic Math Puzzle](https://chrome-stats.com/d/id6752128754) - [Kakuro - Classic](https://chrome-stats.com/d/id6455461477) — 4.70 / 5 - [Kakuro++ Cross Sums Puzzles](https://chrome-stats.com/d/id1445001139) — 4.80 / 5 - [Kakuro Number Logic Puzzles](https://chrome-stats.com/d/id6774941053) - [Kakuro MM](https://chrome-stats.com/d/id1188392230) — 4.70 / 5 - [Kakuro Rally](https://chrome-stats.com/d/id391301051) — 2.00 / 5 - [Kakuro Game](https://chrome-stats.com/d/id1436552307) — 5.00 / 5 - [Kakuro Cross Sums Puzzles](https://chrome-stats.com/d/id1542498165) — 2.30 / 5 - [Real Kakuro™](https://chrome-stats.com/d/id459669325) — 4.70 / 5 - [Kakurasu Puzzle:Brain Training](https://chrome-stats.com/d/id6760905709) - [Play Kakuro!](https://chrome-stats.com/d/id6759475133) — 5.00 / 5 - [KakuroX](https://chrome-stats.com/d/id295531455) — 3.20 / 5 --- Source: [Chrome-Stats](https://chrome-stats.com/d/id306200861)
