Glu Mobile has added 250 new iMessage stickers to its celebrity game Kendall & Kylie.

Players of the game will have access to 50 free stickers for use in iMessage after updating the game. The rest can be unlocked from gift boxes in-game, or by purchasing them through the iMessage app.

It's the first of Glu's celebrity games to add in the feature, likely because of the game's use of stickers within its own mechanics, and its younger target audience being more likely to use stickers in messages.

It's also an interesting move to boost the game's monetisation. While not a fantastic performer, Kendall & Kylie continues to float around the top 500 of the App Store grossing charts.

The original celebrity megahit, Kim Kardashian: Hollywood, continues to outperform Kendall & Kylie, but the older audience and age of the game make it an unlikely fit for iMessage stickers.

iMessages has already proven a fruitful venture for some early adopters. The launch of the iMessage App Store sparked a 74% increase in the number of downloads for Zynga’s popular Words With Friends game.

At the time it was one of the few games companies to integrate into the iPhone messaging platform.
