Gemstone Caverns is a dice game where players are miners trying to collect and sell gemstones. Players roll dice to determine which gem shapes they can collect, then arrange those shapes on their score sheet, aiming to create groups of five or more of the same shape for points. The player with the most points at the end wins. 

Here's a more detailed breakdown: 

• Objective:

  Score points by creating groups of five or more of the same gem shape on your score sheet.

• Gameplay:

  • Players roll four dice, which display different gem shapes.
  • They arrange the dice on a sifting tray, ensuring at least one side of each die touches another along a flat edge.
  • Players then copy the arrangement of gem shapes onto their score sheet, rotating the shapes as needed to fit.

• Scoring:

  • Groups of five or more of the same shape are scorable, and players circle these groups on their score sheet.
  • They count the total number of scorable groups and the total number of individual boxes in those groups, multiplying the two numbers for each shape.
  • These totals are added up to get the final score.

• Strategy:

  Players must strategically arrange the dice to maximize the number of groups and individual gems in those groups to earn the most points.
