If you're having a hard time in Toad Rally, we've got some ideas:
-Try your best to chain moves — bounce from enemy to enemy, and plan your route carefully. The route repeats, so you have some time to figure it out.
-As you land on an enemy, tap the screen — Mario (or Peach or Toad or whoever) will bounce ever higher with each landing and corresponding tap. The game is very forgiving about timing on these, so don't worry about making it perfect. If you look anywhere close to landing it, try tapping the screen.
-Collect as many coins as possible, and focus on the pink coins especially. Your goal in Toad Rally is to impress the Toads that are watching the race. To this end, they like it when you essentially parkour through the level, snagging pink coins as you go.
-If you see a star, prioritize getting to it. Getting a star power-up will vacuum in coins as you go, which is likely to result in a "Coin Rush" (where coins shower out from all over the place). It's a great way to go from doing okay to doing very well.
-If you're losing over and over, try playing against the Nintendo AI character. Or take a break! It's casual. But don't stack a bunch of losses, as it'll dig a hole (every time you lose, some of your Toad friends leave town).
