Stones can have holes formed in them through natural processes like erosion by water, wind, or other elements. Additionally, stones can develop cavities or holes when gas bubbles get trapped during the formation process, which then solidify and create voids within the stone. Another way holes can form in stones is through the presence of organisms like burrowing animals or plants that can create tunnels or cavities in the stone.
Stones can be eroded and form holes due to weathering processes such as wind, water, and ice. In addition, chemical processes like dissolution and oxidation can also create holes in stones over time. Biological factors like plant roots and burrowing organisms can contribute to the formation of holes in stones as well.
Slahal is a traditional Inuit game played on a rectangular board with holes and a set of marbles or stones. Two players take turns trying to slide their stones into the holes while preventing their opponent from doing the same. The objective is to score points by getting your stones into the holes while strategically blocking your opponent. The game continues until all stones have been played, and the player with the most points wins.

This is simply a result of erosion; millennia of churning rocks and sand will yield some with holes in them.

One way to separate stones from grains is by using a sieve or a mesh screen. Pour the mixture of stones and grains over the sieve and shake it gently. The grains will pass through the small holes while the stones remain on top of the sieve.

One way to separate big stones from little stones is to use a sieve or mesh screen with appropriately sized holes. Pour the mixture of stones onto the sieve and shake it gently to allow the small stones to fall through while retaining the big stones on top.
