Apposite Choice Achievement
Place a 10 points letter on a Triple Letter bonus tile.
This achievement requires that you place a 10-point letter on a Triple Letter Bonus Tile. There are only two 10-point letter tiles in the game, the Z and the Q. This is fairly simple to do without much planning since the word you place can be as short as two letters, creating words like ZA and QI. Use the solver if you need, and swap tiles with the other player if need be to get the 10-point letter tiles to your rack.
