TRES is an abstract strategy game for two players, played on a hex grid, with stickered metal nuts.
Each player receives 12 nuts, four each of values 1, 2, and 3. The nuts start in a player's home row, placed in four stacks, with 1 on the bottom, 2 above that, and 3 atop.
On their turn, a player may move one of their nuts from the top of a stack forward (never backwards). Pieces may land on empty spaces or nuts of a lower value (of either player) than the moving piece. Pieces may jump over stacks of nuts equal to the moving piece's value or higher.
If a piece if moved forward again from an opponent's home row, that piece is removed from the game and the player earns a number of points equal to the value printed on the nut's sticker.
The first player to 15 (or more) points wins.
