I only have a V left at the end of the game
I have no other letters left, just a V at the very end of the game. What do I do?All you can do is pass your turn and let your opponent go again. Their next turn might help you unload your V.
If it doesn't, you just have to keep passing until the game is over (either because your opponent uses up all of their tiles, or neither of you can make any more words).
If at the end of the game you have the V still on your rack, you need to subtract 4 points from your total score (because the V is worth 4 points).
If your opponent has used up all their tiles, you also add 4 points to their score (otherwise, they have to subtract their remaining letter values from their total).
I hope that clears it up for you.
