Nine little tic-tac-toe boards, one big board, and every mark you make sends your opponent to the board you just played in.

How to play
Each of the nine cells inside a small board points to one of the nine small boards. Wherever you play, your opponent must play their next mark in the matching board. Win a small board with three in a row to claim it, then line up three claimed boards to take the game.
X moves first; play only in the highlighted active board
If you are sent to a board that is already won or full, you may play in any open board
Claim three small boards in a row, column, or diagonal to win

Tips & strategy
Think about where your move sends your opponent, feeding them a dead or won board hands them a free choice
Centre boards and centre cells stay valuable, just like in ordinary tic-tac-toe
Sometimes sacrificing a small board is worth it to control which board your rival plays next
