The 3 Simulations are the codenames of strategies used by Team Emperor in order to win their races. However, if your opponent is in a different skill level, Simulation X is an exception (particularly on Ryosuke Takahashi) which is race and win at your own discretion.
Simulation 1[]
Allow your underpowered opponent a headstart.
Simulation 2[]
Stay behind your opponent and exploit their weakness.
Simulation 3[]
Overtake your opponent before the finish line.
Simulation X[]
Race and win at your own discretion on exceptional opponents.
