Games that use action points give players a set number of things they can perform each turn. Usually, players are given a set of options and the game allows them to do 2 or 4 of these options on their turn. For example, in the game Takenoko, players are given 2 actions per turn. This could include growing bamboo, adding a land tile to the garden, or irrigating a plot of land. It's up to players to determine which of the actions available to them are the most beneficial to them at the time.
