Overturn - Board Game

Its a combination of Boggle and Scrabble. For 2 or 4 players, age 8+, but I say its for teens+ for a good game. The game is quite simple to learn... There is a grid of tiles that changes for each game. Players take turns looking for words in the grid, like Boggle, and mark their word with colored rings. But if the other player uses those same letters for their next word, they flip the colored rings to their color. The one with the most colored rings at the end wins.
