W.E.L.D.E.R is a word game that takes place on a grid of letter tiles. You get points by moving the letter tiles around to form words. Every time a word is formed, the letter tiles forming the word will disappear, and the letter tiles above will move down to occupy the vacant spaces. Fortunately there’s no time limit, although you do need to form a certain number of words in order to proceed to the next level. You can even unlock different types of swaps, such as swapping a group of letters instead of a single letter. There’s even a built-in dictionary for you to improve your vocabulary while playing.
Swap the letter tiles to form words, though you get a limited number of swaps per game.
