Document 3: Pylos (board game): Pylos is a board game invented by David G. Royffe and published by Gigamic. Two players are given 15 marbles each. They take turns to make a pyramid in a 4 by 4 square grid (note that 15 × 2 = 4 × 4 + 3 × 3 + 2 × 2 + 1). Simple rules allow them to save their marbles — if possible, instead of playing a new marble, a player may rise one of his already played marbles to a higher position, and if any move forms a line or 2×2 square of marbles the player's colour, the player may (and indeed must) remove one or two of his marbles from the board. The winner is the player who completes the pyramid.
Document 4: Stratego: Stratego is a strategy board game for two players on a board of 10×10 squares. Each player controls 40 pieces representing individual officer ranks in an army.

"Stratego" has simple enough rules for young children to play, but a depth of strategy that is also appealing to adults. The game is a slightly modified copy of an early 20th century French game named "L'Attaque". It has been in production in Europe since World War II and the United States since 1961. There are now 2- and 4-handed versions, versions with 10, 30 or 40 pieces per player, and boards with smaller sizes (number of spaces). There are also variant pieces and different rulesets.
