Schnipp & Weg

Schnipp & Weg, first released as Kosakenschubsen, is a flicking game for two players that's played on a game board shaped like an hourglass. Each player starts on one end of the board with nine pieces of their own color. On a turn, you flick one of your pieces at one or more of the opponent's pieces, and if you manage to knock at least one opposing piece from the board while not flying off yourself, you take another turn; otherwise, the opponent takes their turn. If you manage to remove all of the opposing pieces, you start the game again, but with you now having eight pieces instead of nine and with those pieces being one level closer to the center of the game board. Each round that you win, you start with one fewer piece and one level closer to the center. If you win a round after starting on the fifth row with only five pieces, then you win the game.
