Celebrate the Spring by Draining Yuplay’s Profit
Spring time always comes with a sense of freshness and revitalization, so we decided to take a risk make a special storewide promotion that would absolutely kill our profit (and probably get our boss angry). All you have to do to participate is make an order of at least 20€ between 17.03.2026 15:00 CET and 23.03.2026 15:00 CET, and you will get a FREE game coming straight out of our pockets…
Even though Friday the 13th is widely considered as an unlucky date, we at YUPLAY are trying to flip the script for that and turn it into a lucky day for you and this time is not an exception to the rule! We are delighted to announce our FRIDAY 13TH promo and you should absolutely read on the article in order to find out how to best take advantage of this campaign and turn your luck in the right direction for the occasion…
