Overview

Oferhlýp is a free libre open source abstract strategy game played between two players on a 7x7 grid. On the surface, gameplay is similar to checkers (draughts). However, there are several differences:

Tokens may move in any direction rather than just forwards diagonally.
A player’s own pieces may be jumped to create a more dynamic game.
Tokens must be jumped twice before they are removed from the board
Each player has a king token that must be captured to end the game.

Objective

Players try to eliminate their opponent’s king via jumping attacks while protecting their own king.

Starting the game

Players place their tokens on the squares comprising the two rows closest to them with the king occupying the middle square of the edge row. Placement is closer to chess rather than checkers as all squares are utilized regardless of color.

All tokens start at full-strength status with the double rune symbol side up.

Players choose which color (light or dark) to use with the dark color taking the first turn. Players then alternate taking turns.

Playing the game

On a player’s turn, the player may *move* or *attack* with one token.

Moving

Tokens may move one square in any direction onto an open square.
A token belonging to the player may be jumped in a legal move called a friendly jump. Making more than one friendly jump per turn is not permitted.
A player may not follow a move or friendly jump by an attack. A player may not follow an attack and with a move or friendly jump.

Attacking

Players may *attack* an opponent’s token by jumping directly over it to an open square. Attacks are not compulsory.
Players may perform a chain attack by jumping more than one of their opponent’s tokens in a sequence (similar to checkers) following the normal attack rule.
After being attacked, tokens at full-strength status are flipped over to the single rune side to signify that they are now at half-strength.
Tokens at half-strength status are removed from the board after being attacked a second time and are out of play.
Tokens may not be attacked more than once per turn, even as part of a chain attack. Players also cannot simply jump over a token then jump back over the same token.

Winning the game

Players continue to alternate turns until one of the kings has been eliminated.

A stalemate occurs if the two kings are the last pieces on the board as neither player could move without placing their own king into a position which would be vulnerable to anattack.

Perpetual repetition is illegal. If a board position is repeated three times, the player in control of the situation must find another move.
