TWENTY is a fast-moving tile-matching game. Use your finger to drag tiles of the same color and number toward each other, connect them, and then watch these tiles disappear off the grid, which ultimately creates more space on the board. As more matches are made, the numbers will change in sequential order, starting at 5 and advancing until the goal of 20 is achieved. Better move as fast as you can to create as many matches as possible, though, because a new row of tiles will quickly appear from the bottom, pushing the remaining blocks upward. As the game gets more challenging (which is about halfway through at 10), some blocks will appear on the screen, but they will be joined to another number. Match a corresponding tile to the connected blocks to separate them, and then find matches for those blocks to remove them from the board. Your final score is the highest number you've matched before you run out of space on the board, unless you get to 20 and win! Players aim to get to 20 while competing against the game. If you lose the game, no need to start completely over from the beginning: Choose the option to start close to where you left off, at either 10 or 15. The free version of the app also includes the game TwentyTwo, a two-player version of the game, where instead of playing against a computer or virtual player, players will sit in person, on either side of the device and manage the blocks on their side of the screen to beat their opponent. A $1.99 in-app purchase buys different versions of the game, which include Bubble, Flip Flop, Panic, Drop, Thirty, and Zen. Kids who struggle with the speed and timer component may like Zen, because it allows the game to be completed at their own pace, which improves the likelihood of getting to 20, and also reduces the stress and frustration that playing Twenty could cause with the time component.
