Abalone

This game suffers even more than Focus from combinatorial explosion. It unfortunately takes up to five minutes for the server to respond with a move. It's taught me to rather put up simpler games like Hold That Line.

Abalone was invented by Frenchmen Michel Lalet and Laurent Lévi in 1988, and holds the record for awards won including the 1988 Concours International de Créateurs de Jeux de Société, Mensa Select 1990 for Best Mind Game, and was nominated for Spiel des Jahres. Board Game Geek has a page devoted to it with links to videos explaining the rules.

I started a thread on Board Game Geek for anyone who wants to discuss my projects. Feedback on how intuitive my tap targets are would be appreciated. They are very much work in progress on this game.

Rules

The object of the game is to push six enemy pieces off the board.

Pieces are moved in groups of up to three to neighouring hexagons. A group of counters has to form a line in one of the six directions of hexagon neighbours.

A column of three pieces can push up to two enemy pieces on the same line back, and a column of two can push one enemy piece back. The hexagon behind the pushed group must either be free or offboard.

Groups of up to three can also move parallel, but then can't push enemy pieces so a parallel line of neighbouring hexagons needs to be free.

There are alternating moves, black starts.
