WordsAmok! is a fairly simple game that blends elements of Scrabble and Tetris. Seven letters fall slowly from the ceiling – your goal is to make the longest word you can from the letters before they hit the ground or the piles of rubble (i.e. unused letters from previous rounds) below. Long words clear away rubble, and there are special characters that clear away rubble in specific ways (e.g. a pink “e” would clear away all the “e”s in the rubble if you used it in a word; a green letter shears off the top of the highest rubble column).
