Šťastný PUK is a free sports game developed by Generali CZ for Android users. The game is designed to create a virtual league where players are automatically registered as members of their chosen team. The objective of the game is to achieve the longest series of successful shots with a puck into the central circle of a hockey rink and help their team defeat the opponent. The scores of registered players in real-time influence the game's score. Players encounter challenges such as a snowplow and sound waves of cheering fans coming from the left or right side of the stands, depending on where the fans are cheering the most. Players can invite their friends to play the game via Facebook and earn extra lives.

The game introduces new elements such as coin collection, tasks, and a shop for upgrades. Players can use the collected coins to modify their puck, snowplow, flag, or board. Each player starts at level one and automatically receives three randomly generated tasks upon starting the game. Upon completing the tasks, the player advances to the next level and receives a certain number of coins based on the task's difficulty. The results of registered players, their teams, and the last three rounds played are automatically displayed in the virtual league rankings.
