Comments on Knock Out for Android

★★★★★ Lisa S. · Sep 22, 2026

What makes this game so fun? a) The graphics and physics make the smashing experience realistic. b) The UI responsiveness and timing allows for the skipping of fireworks and contest updates. c) The dopamine released from smashing nonstop is addicting. d) All of the above. ✔️

★★★★☆ tina myers · Oct 3, 2026

The game play is challenging and keeps you working to advance your skills. I really like that about this game, they could do better with the rewards and some of the ads are way too long

★★★★★ Tabatha Britton · Oct 4, 2026

I love knock out. It fun, it's challenging. I recommend this game. Review edit... I still love this game however I do have a major issue. There are a couple ads that even after watching the whole ad, I does not allow me the option to close the ad. It only gives the option for the play store. No matter how many times you try the close x never comes up, o ly the play store option. I have to completely exit the game and go back in and it oftn times prevents me from forward progress. Fixable?

★★☆☆☆ Hi Hi Hello · Sep 29, 2026

The game is fun, and like others have said, the physics are pretty good. Some of these levels are impossible without watching (incredibly long) ads, using power ups, so on. There have been multiple times when a block becomes wedged/stuck between platforms after I knock them down, and a power up is the only thing that fixes it. Either there aren't enough coins, or the extra lives/power ups/etc. are too expensive for the frequency that occurs. 20 per level, 600 for 1 item, no other strategy.

★☆☆☆☆ Greg Duke · Sep 27, 2026

Standard rigged style game. They 100% mess with the block weights and other variables, so you'll get stuck on a level, and they'll try and get you to waste some money to get past the level or use a certain amount of lives (watch enough ads) to get through. Just like Candy Crush and merge games and pretty much all mobile games nowadays. Not made to be fun but made to hook people who are predisposed to gambling, relying on dopamine farming to rake in your money. Gross.

★☆☆☆☆ Ethereal Fool · Sep 27, 2026

Malware ad made it seem like a data breach and unauthorized connection happened on phone. Ads open play store by themselves and make you close before you can leave app. Ads have false close button that opened up a link in a web browser or open Google Play Store. One ad looked like I won a prize and needed to claim within a time period, even displayed countdown timer with no close button. Ads hide phone's navigation bar so that it clicked on the ad trying to swipe up to reveal it.
