If you’ve never heard the phrase ‘freemium’ before, you’re more than likely still familiar with the idea. A portmanteau of the words ‘free’ and ‘premium’, freemium games are games which are free to download and play, but which contain the option to buy additional extras. These extras could be new skins, in game currency, or the option to play without adverts. Often these are things which are achievable without paying real money but can be difficult to earn or take a lot of time. For example, freemium game Pokemon GO allows users to buy upgrades and potions using the in-game currency of Pokecoins. You can earn a maximum of 50 Pokecoins every day, but only if one of your pokemon is placed in a gym for the required amount of time. Alternatively, you can buy 100 pokecoins for £0.79, which is a very tempting offer.
