REVERSI VS TAK

Reversi is a strategy board game for two players, played on an 8×8 uncheckered board. It was invented in 1883. Othello, a variant with a change to the board's initial setup, was patented in 1971. There are sixty-four identical game pieces called disks (often spelled "discs"), which are light on one side and dark on the other. Players take turns placing disks on the board with their assigned color facing up. During a play, any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color. The objective of the game is to have the majority of disks turned to display one's color when the last playable empty square is filled. Goro Hasegawa claims that the origin of Reversi/Othello dates back 5,000 years. However, there is solid evidence that a game similar to Reversi/Othello existed since the 19th century. Each of the disks' two sides corresponds to one player; they are referred to here as light and dark after the sides of Othello pieces, but any counters with distinctive faces are suitable. The game may for example be played with a chessboard and Scrabble pieces, with one player letters and the other backs. The historical version of Reversi starts with an empty board, and the first two moves made by each player are in the four central squares of the board. The players place their disks alternately with their colors facing up and no captures are made. A player may choose to not play both pieces on the same diagonal, different from the standard Othello opening. It is also possible to play variants of Reversi and Othello where the second player's second move may or must flip one of the opposite-colored disks (as variants closest to the normal games). For the specific game of Othello, the game begins with four disks placed in a square in the middle of the grid, two facing white-side-up, two dark-side-up, so that the same-colored disks are on a diagonal. Convention has this such that the dark-side-up disks are to the north-east and south-west (from both players' perspectives), though this is only marginally consequential: where sequential openings' memorization is preferred, such players benefit from this. The dark player moves first.

Tak is a two-player abstract strategy game designed by James Ernest and Patrick Rothfuss and published by Cheapass Games in 2016. The goal of Tak is to be the first to connect two opposite edges of the board with pieces called "stones", and create a road. To accomplish this, players take turns placing their own stones and building a road while blocking and capturing their opponent's stones to hinder their efforts at the same. A player "captures" a stone by stacking one of their pieces on top of the opponent's. These stacks can then be moved as a whole or broken up and moved across several spaces on the board. The vertical stacking and unstacking of stones gives a three dimensional element to the game play. A player may move a single piece or a stack of pieces they control. A stack is made when a player moves a stone on top of another flat stone of any color. The stone on top of a stack determines which player has control of that entire stack. All stones move orthogonally in a straight line on the board. There is no diagonal movement. A player can also move a whole stack in addition to single stones. A stack can be moved like a single stone, moved in its entirety one space orthogonally (North, South, East, or West), or it can move several spaces orthogonally by breaking the stack and placing one or more flat stones onto the squares being moved onto. The player can leave any number of stones, including zero, on the starting space, but must place at least one piece for each subsequent move. There is no height limit for stacks, but the amount of stones a player can remove from the stack and move is set by the "carry limit" of the board. The carry limit of the board is determined by the dimensions of the board. For example, if the stack was on a 5x5 board, the carry limit of the stack would be five. Because standing stones and capstones can't be stacked upon, there are no stacks with these pieces at the bottom or in the middle of the stack. Both of these stones however can be moved onto other flat stones to form a stack with them as the head. A capstone may "flatten" a standing stone and use it to form a stack with the capstone as its head, but it must do so alone. For example, a stack with a capstone cannot flatten a standing stone by moving as a stack onto the standing stone, but a stack can be used to move a capstone across the board so that the capstone alone moves to flatten the standing stone as the final movement.
