About Tetraedergame, from BoardGameGeek:
A tactical strategic boardgame involving tipping pyramids to beat your opponent. Tetraedergame is a 3D abstract strategic duel for two players, designed by Rob Mulderij. In this tactical showdown, players control 9 tetrahedral (pyramid-shaped) pieces on a diamond-shaped checkered board, with the ultimate goal of completely dominating the opponent by either eliminating all their pieces or trapping them in a strategic blockade. Each tetrahedron features a specific arrangement of dots (1 to 4) on its faces. The core movement mechanic relies on the current state of the piece: the number of dots showing on the top face at the start of a turn dictates the exact number of spaces the piece must tip over the edges of the triangular grid. A 3-dot piece must tip exactly 3 times, while a 4-dot piece must tip exactly 4 times. Players face tight tactical constraints, as they cannot jump over other pieces or backtrack onto a triangle they just visited during that turn. Combat is resolved through proximity and a unique face-to-face showdown. Instead of landing directly on an opponent, a player initiates an attack by ending their movement exactly adjacent to an enemy piece. The players then compare the number of dots on the top faces of the confronting pyramids. The attacker captures the enemy piece if their top face has an equal or higher value than the defender's. Because ties are awarded to the attacker, offensive maneuvers are highly rewarded. In a high-stakes move, if a piece lands directly between two opposing pieces, both combat actions are triggered and resolved simultaneously, allowing for a devastating double capture. -description from the designer

================================================================================ GAME RULES: TETRAËDER A 3D Strategic Duel for 2 Players ================================================================================ OBJECTIVE: The goal is to completely dominate your opponent. You win the game instantly in one of two ways: 1. LAST MAN STANDING: Eliminate all 9 of your opponent's pieces. 2. STRATEGIC BLOCKADE: Trap your opponent so they cannot make any legal move at the start of their turn. COMPONENTS: * 1 diamond-shaped board consisting of a checkered pattern of black and white triangles. * 18 identical tetrahedrons (pyramids) with dots (1 to 4) on their faces: 9 black and 9 white. * ANATOMY OF THE PIECE: When the face with 4 dots is flat on the board (facing down), the faces with 1, 2, and 3 dots are arranged clockwise around the pyramid. STARTING SETUP & THE FIRST MOVE: Both players set up their 9 pieces in a pyramid shape of 3 rows in their own far corner of the board. All pieces must start with the 1-dot face facing down (flat on the board). The orientation of the pieces from front to back is as follows: * ROW 1 (Front row – 5 pieces): 3 pieces face with the 4 dots forward (towards the center) and 2 pieces (in between) face with the 4 dots to the right. * ROW 2 (Middle row – 3 pieces): 2 pieces face with the 4 dots forward and 1 piece faces with the 4 dots to the right. * ROW 3 (Back row – 1 piece): This single piece sits in the very back corner, facing with the 4 dots forward. THE OPENING MOVE: The very first move of the game is mandatory for both players: you must roll your chosen piece exactly 4 times onto the field. You move in the direction the 4 dots are facing (4 steps forward, or 4 steps to the right if the board edge blocks the forward path). Only the front 3 pieces can be moved on the first turn. MOVEMENT RULES: On your turn, choose one of your tetrahedrons. Move the piece by rolling (tipping) it over the edges of the triangles on the board. * The number of dots on the top face (at the start of your turn) dictates your exact required steps. * A 3-dot piece must roll exactly 3 times (and always ends on the opposite color). * A 4-dot piece must roll exactly 4 times (and always ends on the same color). * RESTRICTIONS: You can never step over other pieces, and you cannot backtrack onto the exact triangle you just came from during the same turn. COMBAT: THE SHOWDOWN METHOD: You can never land directly on top of an opponent's piece. Instead, you attack an enemy piece by landing directly adjacent (side-by-side) to it at the end of your exact movement (3 or 4 rolls). 1. THE SHOWDOWN: Once you position your piece next to an opponent's piece, compare the number of dots on the top faces of both tetrahedrons. 2. CAPTURING: To capture the enemy piece, you must ensure your piece has equal or more dots on top than the opponent's piece. If you do, the enemy piece is captured and immediately removed from the board. 3. THE ATTACKER'S BONUS: Because you win on a tie, attacking is always rewarded! Even if both top faces show the exact same number of dots, the attacker wins and the defender is eliminated. 4. DOUBLE ATTACK (THE FORK): If you land adjacent to two enemy pieces at the same time, you must immediately declare one specific target to attack. You resolve the showdown with that piece only; the other piece remains safe. ================================================================================ THANK YOU FOR PLAYING THE FIRST EDITION! ================================================================================
