Stack Tac Toe (to go)

Stack Tac Toe is a clever variation of classic Tic Tac Toe, inspired by Otrio. With simple rules, fast-paced rounds, and a stackable game format, it's perfect for printing, storing, and taking on the go – thanks to its practical lid. Number of Players 2 players   Objective The goal is to align three same-colored rings (X or O) in a row – horizontally, vertically, or diagonally. Game Variants   1. Classic Tic Tac Toe Played only on the lowest level of the board. No stacking or movement of pieces allowed. The first player to align three same-colored rings in a row wins. Recommended for beginners or children.     2. Simple Stack Tac Toe Played with a maximum of two levels. All players start on the lowest level. Once a player places a piece on the second level, they can no longer place pieces on the first. Only the topmost ring on each space counts. No movement or removal of pieces allowed. Recommended for beginners and casual players. 3. Stack Tac Toe (Free Stacking) Unlimited stacking across all levels is allowed. Players can place pieces on any level at any time. Only the topmost ring on each space counts.  No movement or removal of pieces is allowed. The game ends when a player aligns three of their top rings in a row or when no further moves are possible. For advanced players: more freedom, more strategy. 4. Stack Tac Toe Plus (With Movement) Follows the same rules as Free Stacking (Variant 3). Additionally: If a player has no remaining pieces, they may move one of their own topmost pieces to an empty or stackable space. Again, only the topmost ring on each space counts. For experts in perception and spatial thinking.
