Game

A game was a form of entertainment.

In particular, the Toymaker was heavily associated with the playing of childish and deadly games; (TV:, etc.) the Sixth Doctor would later describe games as the Toymaker's "meat and drink". (PROSE: )

History
In the 3rd century, the Doctor used the game of chess to imprison Fenric in the Shadow Dimensions. (TV: )

The Toymaker's games
In the Toyroom, which seemed to display no correlation with the passage of time in the universe, (COMIC: ) the Toymaker played many games, turning those who lost into toys, cheating and lying to maintain an advantage. (TV:, etc.)

The Toymaker once lured professional gambler Gaylord Lefevre to the Toyroom to play a game of cards with him, but declared the game forfeit when he found that Lefevre tried to cheat him. (COMIC: )

After compiling a list of games to play, choosing hopscotch, Cards against Humanity!, Hunt the Key, the Dancing Floor, Musical Chairs, Blind Man's Bluff, and the Trilogic Game, and crossing out Oranges and Lemons, Charades, Sardines, Sleeping Lions, Musical Statues, Consequences, Pass the Parcel, and Pin the Tail on the Donkey, (PROSE: ) the Toymaker once forced the First Doctor to play his Trilogic game while he forced his companions, Dodo and Steven, to play Blind man's buff and hopscotch with his clowns Clara and Joey. The Toymaker gave the Doctor only 1023 moves to finish the game, or he would be trapped in the Toyroom forever. The Doctor used voice control to place the last piece. (TV: )

After the Eighth Doctor and Izzy Sinclair entered the Toyroom, they were forced to play snakes and ladders and hangman. After the Toymaker created a duplicate of the Doctor and made them compete in a game of gladiatorial chess, he placed Izzy and Maxwell Edison in a game of mousetrap. (COMIC: )

When the Twelfth Doctor and Clara Oswald were lured to the Toyroom, they tried to escape Krampus through snakes and ladders. After losing Krampus and encountering the Toymaker, he and the Doctor played Truth or Dare, where the Doctor got the Toymaker to explain why he too could now also control the Toyroom and the Toymaker dared him to forfeit. (COMIC: )

The Toymaker once tempted another victim with the Trilogic Game. (POEM: )

The Toymaker, now going by "the Mandarin", had wanted to challenge the Entity to a game for a while. Upon travelling to the Entity's domain, they played a game of four dimensional chess. (PROSE: )
