Inzert XO: 2 players, 1 device – brainy tic-tac-toe with forced moves and symbol flips

Summary: Inzert XO is an offline two-player tic-tac-toe variant where each move directs the opponent’s next play and includes a flip mechanic to take over symbols. The goal is to align five symbols in any direction on one device.

What it does

Players alternate moves on a board where each field dictates the next move’s location, with an added flip move to capture opponent symbols. The game ends when a player aligns five symbols consecutively.

Who it's for

It is designed for two players sharing a single device in pass-and-play mode.

Why it matters

It introduces strategic depth to tic-tac-toe by forcing moves and enabling symbol flips, increasing gameplay complexity offline.
