Hello guys, I would like to recommend you a fun and challenging number game – Make11. It is a game which enables you to learn in seconds, but play for hours~ Although Make11 is a free to play game, its well-made gameplay can make you fully obsessed with it. Just click on the screen, select the right location to drop the number. Blocks at the same number will compound to a bigger number. Be careful, the game can be really fun to play! https://play.google.com/store/apps/details?id=com.zplay.makeeleven
