It's like Scrabble and Bananagrams but way faster and funner.
One Up! takes a nimble mind, as everyone tries to be the first person to make a word from the tiles that are turned over in the center: first an "A", then an "R" and then a "T". Shout it out, and don't be shy: "ART!" Wait a sec – the game has a cool, cutthroat twist: any player's words can be stolen by anyone else by simply adding a letter. If an "M" is turned over, and since you already have the word "ART", I can call out "MART" and take it from you. It's my word now, so pound sand!
But you can snatch it back if an "S" is flipped over and you yell out "SMART." Damn. Just remember that all words are in play at all times, so you better be able to think fast on your feet. Show zero mental mercy – steal away!
No board. No complicated rules. No monkeying around – just wicked/smart cheap thrills!
