Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.
Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.
We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.

About 15 Defense Key
I went in expecting either a joke or a hidden gem. 15 Defense Key is neither - it's a straightforward, no-frills tower defense experience that does exactly what its minimalist title suggests. You place defensive structures to stop waves of enemies across fifteen levels, and that's the whole loop. There's no story, no prestige progression, no meta-unlocks. The interface is functional but bare-bones, and the difficulty curve flatlines quickly. The appeal here is pure pick-up-and-play: if you want to spend twenty minutes clearing a defense scenario without menus or complexity, it delivers. But it also delivers almost nothing else. No build variety, no strategic depth, no reason to replay once you've cleared the campaign. It's the kind of game that exists because someone made it, not because they had a vision to execute. Fine for a five-dollar impulse buy if tower defense is your comfort food, but don't expect surprises.
