The game is divided into tons of levels that you have to beat by reaching the minimum required score. To do this, you have to form complete words using all the letters you see in the middle of the screen, tapping each one as you put the words together. You'll see the letters in red until you form a valid word, and then they'll turn green. Each letter has a small number representing the score you'll get for playing each one. The longer the word you create, the more points you'll get. But it's a good idea to use letters worth more points, too.
With this app, you can improve your vocabulary or learn new words in other languages. Bubble Words Letter splash has dozens of levels and as you advance in the game, you'll find new challenges. Find the best words you can and get as far as possible.
