★★☆☆☆

I'm very disappointed with this game. I played all the others and was excited when Brain Test 5 came out. I can understand tricky puzzels but a lot of these just don't make sense, hard to figure out. It doesn't get easier it got more complicated as it goes along because you only get a limited amount of tries and then when you loose lives you have to wait a certain amount of time to play again. Because I don't want to loose lives I'm watching a bunch of ads to get clues. Just very frustrating.

The game is literally unplayable. You play part of a level, an ad plays, the ad automatically takes you to the app store, you go back to the game and the app reloads and you have to replay the level you just played, at which point another ad plays and the cycle begins again. I enjoy the game, but I literally can't play it with how the ads work.

I'm so happy to have another Unico game in this series! These are the best games I've ever downloaded, by far! I've played all of the others to completion, and when I saw BT5 pop up, I couldn't download it fast enough! Tiny puzzles mean you can hit a level or two while waiting in line, going to bed, etc. Cute format. Same characters... WINNER! 😁👍❤️❤️

This last iteration of Brain Test presents puzzles on steroids! You think you've mastered all of the previous games? Think again, because they introduced a mistake counter that limits your moves. At first, I didn't like it. But the added challenge provides more excitement in the long run. I was constantly on my toes to avoid any wrong moves. And they actually offer plenty of mistake chances so that you can try and learn in most levels. I also loved the enhanced graphics and animations. The best.
