Cross Words

Tap a tile then a square to spell a word reading across or down, crossing the tiles already on the board. Your first word must cover the centre star, and every run of letters must be a real word. Premium squares boost the score (DL/TL double or triple a letter, DW/TW the whole word); use all seven tiles at once for a 50-point bonus. Swap exchanges tiles; Pass skips your turn. Arrow keys or a gamepad move the cursor; Enter places.
