Nickelodeon Kart Racers 3: Slime Speedway

PS4 / PS5

Before starting the 40 cup wins, test Slime Speedway’s three multiplayer setups. Local races, a private race with a friend and public matchmaking cover different requirements. For solo work, begin with challenges: they unlock crew members that can make cups and ghost races more manageable.

Third Nickelodeon Kart Racers game, with native 27-trophy PS4 and PS5 sets. The Turbo Edition is optional.

  • Native sets: 27 trophies each on PS4 and PS5.
  • Multiplayer: Five online trophies, plus 20 local races with a second controller.
  • Solo route: 48 challenges, 36 ghosts and 40 cup wins.

Arrange the private race and four-player race

For Always Better with Friends, create a private race with a friend on the same version. For Harmonic Convergence, use online matchmaking, get at least four people into the race and stay through the results. Public matchmaking can bring PS4 and PS5 players together, while the documented private route uses the same version.

  • Check these trophies early: trackers show 2026 four-player unlocks, but lobbies can be quiet.

Reach 1,150 matchmaking points

The independent guide records a 1,000-point starting score: look for 1,050, 1,100 and 1,150 for the three rewards. Use Online Matchmaking for these counters; a private race does not replace it. Losses can take points away, so check your total before reentering a lobby.

  • Grandmaster is recorded on PS4 in September 2026 and PS5 in summer 2026; test matchmaking on your version.

Unlock crew through all 48 challenges

Work through six groups of eight challenges and read the objective before starting. Challenge 3-6 unlocks Mrs. Puff, who helps with blue-spark drifts. For Drift Beeper King, land 21 blue boosts in the same cup: pick a familiar cup and hold the drift through long corners rather than ending it early.

  • Check all eight results in each group, including ones that do not unlock a character.

Win 40 cups and beat all 36 ghosts

Krushing It requires 40 first-place cup finishes: you can repeat a cup you win reliably. Read the Double Dares at the start to complete them while working toward the cup total. Then take on Time Trials, pick the intended ghost for each course and learn shortcuts before risking a jump or tight line.

  • Check the beaten ghost total separately from cup wins.

Finish local races and racing counters

Connect a second controller, enter local multiplayer and finish 20 races. Then use an eligible Arena mode for the ten wins. Spend your rewards on shop purchases and check the wash, item-hit and stunt counters; for wave-edge stunts, use the edges of waves in water sections.

  • Make a dedicated run for wave-edge stunts if that trophy is still missing.

Frequently asked questions

Does a private race cover every online trophy?

No. Private is the route for the race with a friend. Points come from matchmaking, where you can also arrange the race with at least four people.

Must I win 40 different cups on the highest difficulty?

No. Forty first-place cup finishes count, and you can repeat the same cup. Pick a difficulty where you can win consistently.

Do I still need a second controller if I play online with friends?

Yes. Ewww Humans! requires 20 local multiplayer races. Online matches do not add to that counter.
