They’re Stratego Pieces!
Stratego or /strəˈtiːɡoʊ/ is a strategy board game for two players on a board of 10×10 squares. Each player controls 40 pieces representing individual soldier ranks in an army. The objective of the game is to find and capture the opponent’s Flag, or to capture so many enemy pieces that the opponent cannot make any further moves. Players cannot see the ranks of one another’s pieces, so disinformation and discovery are important facets to gameplay.
