         "frogger": "As in other Decktet games at Abstract Play, the deck is displayed at the bottom of the board and includes both cards in the deck and unknown cards in other players' hands. After the first hand, all cards are drawn from the open draw pool, so hands gradually become open. The discards pile is also displayed.\n\nDue to how randomization works at Abstract Play, forced passes are needed for a player to refill the draw pool in the middle of his turn. Passes are handled automatically by the server, but a there's also a draw pool variant that avoids forced passing if desired.\n\nThe Crocodiles variant is by Jorge Arroyo, the translator of the English rules. The Advanced rules and other minor variants are by P. D. Magnus; they appear in The Decktet Book, where the game is called Xing.",

The game was designed by [George Howard Monks](https://en.wikipedia.org/wiki/George_Howard_Monks) in 1883/4. It is said that Halma was inspired by an older British game called *Hoppity*. However, this game has no documentation or surviving boards, turning this lineal statement into a historical mystery. Halma was later adapted (c.1892/3) into an even bigger success: [Chinese Checkers](https://boardgamegeek.com/boardgame/2386/chinese-checkers) (which could easily be played by three or six players).",
