This is the route I do to gather all coins necessary. Which is why I do the last 2 minigames after everything else. x2 = doing the same mission twice before moving on. x3 = doing the same mission thrice.

• Robot Beach: Eye Ninja Heart Attack Eye 2 Eye Eye Ninja 2 Heart Attack 2 Eye 2 Eye 2 Kyza Fly Ninja Ninja Ball Eye 2 Eye 3 Heart Attack 3 Eye Ninja 3

• Bomb Bay: Shoot the Ships x2 Grade in a Cage x2 Rocket Factory x3 Ventis Chase the Fuse x3 Grade in a Cage 3 Chain Challenge Ninja Ball Ultra

• Jungle Falls: Psyamon Ride the Logs x3 Buzz-Off! x3 Sly-Ninja x3 Jump ‘n Grind Ninja Ball Extreme

• Mountain Gorge: Sneak and Destroy x3 Clouding Around x3 Crystal Cavern x3 Malakai

• Moon Base Outpost Alpha x3 Outpost Beta x3

The Cryo-Chamber x3 The Imperial Guard x3 Emperor O-Dor

Credits skip (Just save after beating O-Dor, close game, re-open.)

• Back to Mountain Gorge Mega-Chain Challenge Egg Shell Skull

DISCLAIMER: Both of these challenges accumulate a total cost of 1800 coins. In this route farming in the imperial guard/cry-o chamber is a viable last resort if you realize you're running short!

Immediate warp to Robot Beach after 100% completion

The Battle Arena

And done!

BIG, FAT WARNING: If you're doing skips (Ride the Logs, Rocket Factory, Buzz-OIf etc) remember that EVERY COIN MATTERS in 100%. 1800 for the final 2 challenges is a brutal amount so pay close attention to your coin total whilst running it. Good luck!
