I see the twitch skin but the hint is really vague on how to get it. Can someone help me?

Every time I play a game, especially on a colossal map, I can't help but wonder how many tiles there are. It's easy enough to work out for the cube shaped maps. but I was wondering if anybody knew for the other shapes/sizes? I don't know why I'm surprised nobody's asked this yet (I checked)....

I've sunk 11 hours into this damn game, at least 10 of which are attempting to get the colossal achievements. I can't do it... The thing is, I know how to beat them, but eventually, in a 2 hour session, my brain slips up or I missclick. I don't have the mental strength to keep sinking hours into this game to no avail. Why can't there be some sort of life system where if you clear 1000 empty spaces you can click one bomb without consequence? Otherwise I don't think I'll be able to finish a colossal globe....

Why does this game require internet connection to work properly? Am I the only person who has issues with this game when playing offline/airplane mode? Tiles do not reveal when I click them while offline/airplane mode, I have to save and quit, then reload the game to make them appear....

This is a terrible design decision devs. It's a pure grind, with no difficulty at all. I actually love the difficulty of the colossal in like 50 min, because it's a doable challenge. But 1000 games, while obviously doable, has zero point to it. I'm quite good at Minesweeper (played a lot at work during slow times), so I can beat an easy level in like 25 seconds or less quite consistently, but even then, it's going to take like 8 hours of just pure grind on easy levels to get it. Who could think of this as ...
