A GAME OF WORDS. Find and eliminate words [in a grid a letter tiles]. 4 puzzling modes. Longer words, larger rewards. Tackle tiles and keep your tower low. 4 SINGLE PLAYER MODES: 1. TOWER MODE. No pressure here. Try and get the highest score possible out of 150 letters, eliminating small words to set up 7- and 9-letter block busters! 2. PUZZLE MODE. Every word you make adds a new row of letters! Strategic word finding at its best. 3. EXTREME PUZZLE MODE. Like Puzzle Mode, but with the minimum word length cranked up. Experts only! 4. RUSH MODE. Row of letters build up over time. Find words as fast as you can, but be careful you don't back yourself into a corner! [Also, there is a DEBATE MODE for 2 players with two devices (and two copies of the game) to compete via Bluetooth.] For more, see the the publisher's website at spelltower.com.
