Add house rules that allow you to TAKE money from players rather than add it. The idea is to bankrupt players as quickly as possible.
don't give money for free parking, as stated in the house rules
remove some chance cards that bring in money
gradually reduce the GO money after a couple of rounds
reduce the jail time so people interact more with properties
start with less money
Speeding up Monopoly Go mostly comes down to having the right stickers to finish albums faster and trigger big rewards like free dice and cash boosts. The grind for stickers can get brutal especially near the end of an album when you’re only missing a few rares or golds. Trading helps but it’s slow and depends too much on luck and community timing. Easiest method is to buy Monopoly Go stickers directly so you don’t waste hours waiting for trades or hoping they drop. I’ve done it during Sticker Boom and it made a huge difference. Delivery is instant and the process is simple. Great during limited events where speed really matters.
