I’ve tried a lot of online games while living in Korea, and most are either too flashy or don’t support English properly. But https://plinko.kr/ was a nice surprise. It’s incredibly straightforward, and even though I went in just to kill five minutes, I ended up playing longer than expected. There’s no stress or complicated mechanics—just drop and hope. The fact that the entire interface is in English makes it actually usable for non-fluent players here, which is a huge plus.
