If you’re aiming to 100% Go Kart Island, the good news is it’s pretty straightforward. The game doesn’t really try to hide things from you, but a few achievements can still trip you up if you don’t know where to look.
I went through everything carefully, and here’s a clean, no-nonsense breakdown of how to unlock every achievement without wasting time.
Story Achievements
You don’t need to stress about these. Just progress through story mode and you’ll unlock them one by one.
Here’s what each one involves:
- Circuit Racer → Win any circuit race
- Time for an Achievement → Complete a time trial
- Check You Out → Win a checkpoint race
- Collector → Complete a collect event
- No Coin Left Behind → Win a collect race
- Pursuing Greatness → Complete a pursuit event
- Street Racer → Win a street race
- Cheating Death → Win a death race
- By the Skin of Your Teeth → Complete an escape event
- Eliminator → Win an elimination race
- Crazy Driver → Complete a delivery event
Big Progress Milestones
- Taxable Income → Collect enough coins to enter the Mayor’s BIG RACE
- Go Kart Champion! → Win the BIG RACE
Just keep playing the story and these will unlock automatically.
Collectables
The game helps you a lot here because everything is marked on the mini-map.
What You Need:
- 100 Coins → Spare Change
- All Billboards Destroyed → Election Interference
- All Gems Collected → Treasure Hunter
Tips
- Zoom your map and clear areas one by one
- Don’t rush this early, clean it up after finishing most races
- Gems are slightly trickier, so keep an eye out for hidden paths
Ski You Later
Head to the ski slope area.
What to do:
- Drive downhill
- Hit every flag on the slope
Miss one, and you’ll have to run it again, so take a steady line instead of rushing.
Goal Kart Island
Behind the hotel near the rich area, you’ll find:
- A football (soccer ball)
- A goal post
Push the ball into the goal to unlock the achievement.
Important Tip
If the ball gets stuck or rolls away:
- Quit to menu
- Reload the area to reset it
A New Perspective
- Open Settings
- Go to Gameplay
- Change camera to Perspective
That’s it, achievement unlocked.
Misc Achievements
These are small but easy to overlook.
Honk If You’re Horny
- Just honk your horn outside the tutorial
Shortcut
- Enter any cave or tunnel on the map
You’ll probably unlock this naturally while exploring.
Lick of Paint
- Find a different colored kart somewhere on the island
- Then go to the paint shop
A waypoint usually appears after picking up a kart.
Perfect Start
- During race countdown, press accelerate at around 1 second
Timing matters. Too early or too late won’t trigger it.
Up for a Challenge
- Unlock Challenge Mode (after a few story races)
- Win Gold in any challenge
Bonus Tricky Gem
This is the only collectible that might actually slow you down.
Where to go:
- Head to the ski slope
- Enter the train tunnel nearby
The gem is hidden inside that path.
This is one of those games where 100% completion feels relaxing rather than frustrating. Nothing is overly grindy, and most achievements come naturally if you explore properly.
The only real things that slow players down are:
- Missing the ski flags
- Not knowing the ball resets
- Overlooking that one hidden gem
Handle those, and you’ll have a clean 100% without much trouble.
