New update put ads back on my version and unable to restore purchase. App support is sn over seas help number. **Developer response:** Dear users! we will fix this in the next version of the game, we apologize ### 1/5 — Update has rendered the game useless! *2020-12-03, version 1.2* This game no longer works. Whatever you did is not working. Everything is blank. No way to choose the blocks. There are no blocks anymore. **Developer response:** Dear users! if you have such a problem, then uninstall and re-download the game and everything will work correctly. We are sorry. This is due to the addition of the leaderboard. ### 4/5 — Stopped Working! *2020-08-23, version 1.1* I LOVE this app and I would love to give this five stars, but after playing about a month, the ability to watch an ad for 30 seconds to be able to rotate a block or reverse a move just quit working. Either the ad didn’t play at all, the ad played but never allowed me to go back to the game, or kicked me out and started a new game. I just deleted the app and am reinstalling because I love this game. It’s totally addictive and I want to keep playing, but not the way it was working. **Developer response:** Dear Geminigirl621, thank you for feedback. We are working now on a wide update which will cover all the issues that you’ve mentioned. ## Frequently asked questions about TetroBlock ### What is TetroBlock?
