Hello,
People think by installing games is a way of entertainment however the reverse thing is true.
Even if this is not about gambling or depositing money to win something, developers of the games are some people very tricky.
They offer you free bonuses to reach a high level but after that progress in the game, you will realize that what works before with showing an ad with a mobile phone could never work if you reach a high level like level 47.
Then to continue work they offer you an item on the shop to buy 2,99 $ for example and without this item, developers of the game will never let you pass to the next level until this item is purchased.
They also could suggest a starter package but they know if you have succeeded in many games, the chance of uninstalling the mobile application will be a lot reduced then they go to the next step then the game becomes purchased to continue and no longer for fun purposes.
