Official rules
Arcade Mode arrived in v1.5.0. The update specifies 10 random simulations and randomized rounds. It also removes the intro and outro to reduce waiting.
What random means
The official note does not publish a fixed order or guaranteed selection. A guide therefore cannot promise that a specific minigame appears in a run. Strategies must be attached to the simulation actually selected.
Runtime is not fixed here
The mode is described as faster, but the source does not give a universal duration. Player decisions, round outcomes, and the selected simulations can affect elapsed time. This site does not invent an average session length.
Arcade versus standard flow
The verified difference is streamlined presentation and a 10-simulation random format. Claims about rewards, scoring changes, difficulty scaling, or exclusive content are not supported by the cited update. Those details remain unconfirmed.
