SpellStaX
How to Play
Letters fall onto the board in stacks (ala Tetris). Move them left or right and rotate them as they fall. You can also scramble the letters in the tiles to move them in a more useful position.
Create valid words (3 letters or more) horizontally or vertically across the board to score points. Each letter has a value based on their value in Scrabble (shown on the letter tiles). The valid words are taken from the Scrabble dictionary. Valid words are highlighted in gold briefly and then removed from the screen as the columns collapse ala Tetris. These words are also shown in the gold box on the right side of the screen.
The game runs against the clock (currently 4 minutes), so think fast! When time runs out, the game ends. Use the restart button to return to the intro screen to start a new game.
On mobile, use the on-screen buttons to move, rotate and scramble the tile letters. On desktop, you can also use the keyboard (left and right arrow keys, space key to rotate and enter/return to scramble tile letters).
Tip: Plan ahead — smart placement makes better words and higher scores!
