Analytical Solution for "EinStein würfelt nicht!" with One Stone

“EinStein wurfelt nicht!” is a simple board game, played usually on a \(5\times 5\) board with 6 stones per player and a die. In this research, we study the game in the particular case when the players start with only one stone. In that case the random element from the use of a die disappears, so that an analytical analysis is possible. We describe and prove a winning strategy for the first (or second) player for all possible board sizes. In most cases, the first player can force a win, but somewhat surprisingly, depending on a precisely formulated condition on the board size, it is sometimes possible for the second player to win.
