I know this is available on pretty much every device but I just wanted to give everyone a heads-up that the Switch version specifically is now awesome. They've just patched it so it runs at a consistent 60fps in handheld mode which, combined with the ability to turn the Switch vertically and see the whole table, makes it pretty much the definitive version as far as I'm concerned. Leaderboards are cross-platform and it's all pretty great. As it's a free download with one pretty good table included, it's worth checking out if you have even a passing interest in these things.
The only drawback with the Switch version is that, due to licensing issues, the many Marvel and Star Wars tables are currently unavailable - however the devs are working to resolve this and they're expecting them to become available further down the line. Most other stuff is there for download. Anyone got any particular recommendations?
