The game "Wellen-Halma" was included in Spielbox 4/90 as part of the "Spiel im Heft/Game in the zine" series. It is played on a 8x8 grid board with 5 specially marked 2x2 squares. Each player has 12 playing pieces which are placed on the board at fix positions. 4 neutral pieces complete the starting position with all 28 pieces on the board. Object of the game is to either occupy one of the five 2x2 squares with his own pieces or form one of 2 special pentagons anywhere on the board. The neutral pieces can be counted as own pieces by both players. Each turn, a player can move a playing piece either 1-2 straight spaces in one of the 8 directions or by making a chess-knights move. The name "Wellen-Halma" (="Wave checkers") comes from what follows after a playing piece has moved: all adjacent playing pieces are moved away for 1 space, if the are not protected by pieces behind them!
