Everything you need to know about Press the Button.
X-Frame-Options. We check for this ahead of time by reading each site's actual response headers rather than guessing, so instead of showing you a blank screen, those specific sites show an "Open in a new tab" button instead. Sites like CrazyGames, Newgrounds, and JetPunk fall into this group, among others. The check isn't run on every single press โ it's done when a site is added or periodically re-verified โ so if a site changes its policy later, the classification can occasionally lag behind until the next check.
