The new features – score hiding or making it to appear/disappear – offer a gamification element in multiple game plots: 

• A game where the team’s score is hidden for all players (including the team itself) throughout the game. The game instructor will reveal the winner after the game; 
• A game where the score will be available at the beginning of the game but will be hidden in the end. That will be a surprise moment for the team who’s the actual winner. 
• A game wherein the beginning of the game, the score is unknown. But it will be revealed at some point in the later phase of the game. We can imagine that the teams are going to pull together to take the last chances to win. 

Allowing the in-app leaderboard is a crucial feature to support the score appearing/disappearing functionality. Here’s the reference on how to apply to your game: https://loquiz.com/2018/11/06/show-teams-locations-score/ . It offers a comparison moment for the teams. 

Yet, this feature is not thoroughly for gamifying the game, but score hiding is for instance is for the game formats, where the emphasis is not lying on score collection.
