variations or special demands players can make on game solutions. Adventurous games have a series of variation possibilities that may apply and increase in difficulty as players age. Games Played Eight games are played in official AGLOA tournaments. Some local leagues also play other games such as On-Words (a simplified version of LinguiSHTIK). Math Games Two math games, Equations and On-Sets are played at AGLOA tournaments. Equations Equations is a mathematics game created in 1965 for 2–3 players. The game uses a playing mat with Forbidden, Permitted, and Required sections and 24 cubes, each labeled with numbers and mathematical operations. At the beginning of each "shake", one player uses up to six cubes to set a "goal." All players must use the remaining cubes to devise a solution that equals the goal or win by challenging an impossible board + goal situation. Gameplay can become more complicated through the use of "variations" called on the game. Applicable variations differ by the player's age division. The game progresses with each player moving one cube on their turn, or alternatively challenging that they can create a solution with the cubes in play, that a solution was possible on the last turn and the player before had missed it, or challenging that it is impossible to create a solution with the cubes available. When a player calls a challenge, it is called against the player who most recently completed their move. In a three player game, the indifferent player may choose who he sides with in the case of a challenge. A player who correctly challenges another player wins the game. The loser of a game gains two points, The winner six, and the sider (if he sided with the winner) gains four or two (if he sided with the loser). Equations games become more intricate with the use of factorials, vulgar fractions, and even logarithms, in the Senior division. On-Sets On-Sets is a board and cube game that teaches basic logic and set theory. This game also uses a deck of 16 cards that is used to make the "Universe". Each card contains a different combination of colored dots. The cubes contain numbers, colors and logic operators. Players learn logic concepts such as union and intersection, and learn to use restrictions such as subset. Variations can also be used in On-Sets games. A player wins by using the cubes in resources to
