Developers are increasingly using virtual currencies to monetise their device or tablet games in a bid to boost user engagement within games.
Tablets are all set to play a major role in growth of mobile games, as tablet gamers are predicted spend more than $3.03bn on in-app purchases by 2016, according to a new report from Juniper Research.
However, smartphones are expected to dominate as the primary device for in-app purchases, as they are anticipated to generate about $6bn, which is double the amount purchased over tablets.
Juniper Research research analyst, Siân Rowlands, said: "When we consider that only a small amount of gamers actually make in-game purchases, and those that do typically only spend a few dollars, it becomes apparent that there are a small proportion ofconsumers spending thousands annually on these virtual currencies, who subsidise the game for everyone else."
The report says that developers are increasingly using virtual currencies to monetise their device or tablet games, rather than offering in-game items or pay-per-download titles.
Some of the games including Slotomania, Poker by Zynga and Texas Poker witnessed a sharp rise in the number of users purchasing chips and other in-game items, the report revealed.
