host on the tv
Put the board on the big screen. Pick best of five or best of ten, then share the code.
two players. nine squares. nothing sits still for long.
The game you already know, with one twist. You only ever keep three marks on the board, so your oldest one disappears the moment you play a fourth. Get three in a row before the board rearranges itself under you.
from the room
Same board, same three-in-a-row goal, one new rule. Nobody ever holds more than three marks at once, so the oldest one on the board vanishes the moment its owner plays a fourth. The board never fills up, and neither player ever runs out of moves.
Pick best of five or best of ten in the lobby. The match score stays on screen the whole time, and the host alternates who opens each round so nobody has a permanent first-move advantage.
Two players, one phone each. Best part: whoever loses can demand a rematch immediately.
the short version
One host on the TV. Everyone else on a phone. The room does the shouting.
Put the board on the big screen. Pick best of five or best of ten, then share the code.
Name yourselves and draw a quick portrait. This one's strictly a duel, so it needs exactly two.
Tap a square on your phone when it's your go. Once you've got three marks down, the oldest one is marked to vanish next turn.
Line up three in a row to win the round. Win enough rounds to take the match. There's no draw to bail you out.
