A strange little side quest
Here is a rabbit hole for the next loading screen in The Winter Game: Hidden Object: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. There is another connection worth keeping in the same mental pocket: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That gives The Winter Game: Hidden Object a little more company than it first appears to have.
