Sudoku is a Japanese logic game where the player must fill a 9x9 grid with the numbers 1 through 9. Each row, column, and 3x3 box (also known as regions, blocks, or boxes) contains each number exactly one time. So the same number cannot be in the same row, column, or 3x3 box. Once you fill the whole grid correctly, you win.
The matching game is a memory game that contains cards where each card has a matching picture. The objective of the game is to turn over any two cards (one at a time) that you think will have the same picture, and if they do, and the player keeps them. They must successfully match as many pairs as they can, and once all the cards are collected, the game is finished.
A choose your own adventure game is where the reader/player goes through a story that is written from a second-person point of view, with the reader being in the role as the protagonist and gets to make choices that determine the protagonist's actions and the plot's outcome, kind of like a RPG.
