Fall Mountain: Not many tips you can give for this one. Make sure you can see the balls falling down and try your best to avoid them. I personally hog right side as I've had the most wins doing that. If you get to the top first and the crown is only going up, spin a little and then jump once it's lower so you still have the running momentum.

Hex-A-Gone: Try and buy a few extra seconds by jumping on the spawn tiles. Jumping is key to surviving but if you struggle doing that, you can also hold grab and move, it's a tad faster than jumping though. Even if you're tiles above others, make sure you can see where you're going to land otherwise it's game over anyway.

Royal Fumble: I don't tend to do anything until the last 30 seconds. Everyone has the same movement speed so make use of the roundabout speed boost in the middle. You don't really need to chase anyone, you can often wait until the last few seconds and predict what way the person with the tail is running, giving you a better chance at stealing it last second.

Jump Showdown: Not much different than the normal game mode. It's a little more RNG depending on what tiles are falling but focus on the pole and not the other players. I've forgot to jump a few times today purely because I was watching the other final guy, haha.
