And now, Threes! is available in the ay store for your Android device, as announced by the official twitter account. In Threes!, you slide a field of cards left, right, up, down. If another card is in the way, that row/column won’t move. If a card has the same number, they combine double up. en there are no more moves to make, the game is over, you earn points for the cards you have managed to combine to high values. — Threes (@ThreesGame) h 12, 2014 It sounds simple, it is, but it’s also ferociously addictive clever. You’ll find yourself unable to stop without “just one more game”, looking up from your phone to realize that the quick game break you planned on has suddenly become an hour of wasted time. It’s two bucks on ay, it’s totally worth it.
