“In Holland, the game of Sjoelbak or Sjoelen came about probably in the late 19th century. In this, 30 disks are aimed down a six foot table in an attempt to get them through 4 arches numbered 1 to 4 at the other end. However, a cunning twist compels players to attempt to get an even number of disks through each arch because each set of disks in all four compartments scores double.
By the 1800's Shovelboard had been abandoned by the aristocracy and nowadays, Shovelboard tables are confined to museums in England but it's direct descendant Shove Ha'penny still thrives and major derivatives also developed in Europe and in America.
In England, during the 15th century, an indoor version of Shovelboard for play in taverns developed called Shove Groat or Slype Groat and this has been played ever since, evolving into the game known today as Shove Ha’penny.”
The may be some connection between Groat and deGroot.
