From those 3 games your average round is 31. How many downs did you have in those games. Downs in low rounds affect your rank more than in higher rounds. Keep getting above 30 and don't go down. Playing custom games allows you to end the game if you get cornered and not take a down as " solo" mode if you get cornered and end it you can still get downed. Easy mode can rank you up as well but there is speculation on how much more original difficulty ranks you up more than easy difficulty.

Side note K/D does not matter at all. Ppl have ranked up on buried using the buildables without any kills. It's all rounds to downs.

1 down for the last 2 games and 2 downs for the first game

It's doesn't sound like a lot but if you wanna rank up you cAnt have any downs . Going from the skull to machete ( rank 3 to rank 4) is probably the biggest jump. Having the knife means you have skills and know what to do. Having the shotguns means you have honed your skills and can easily bounce back no matter what round. This statement applies to non glitchers. Glitchibg is cheating and cheating is easy. Playing for real takes skill and patience.

Play easy for a couple games on one map . After you feel comfortable with the map and your strategy(ies) go play original.

Buried is good to rank up because of camping in the Jugg alley with PAP guns and the trample steam should easily take to to 30 .

at round 26 so far with 1 other person online, one guy left though so it wont show up on the leaderboards the way we're going we could easily get to 40

Even if ppl leave you can rank up so unless your going for a leaderboard score I wouldn't worry about it.
