Solo rush mode: "45 minute Lunch"
Pick a truck and it's owner card and starting order and place those appropriately on you board.
Place 5 trophy tokens as the base of the 5 stacks and in order starting with the number 1 place the numbers 1,2,3 on top of each of the 5 trophies. So you should end up with 5 stacks with 1,2, 3 and then the trophy. These trophies represent rating stars from your customer. For every pile you clear off you get that star and instead of placing a 1,2 or 3 token on your board to expand a part of your truck you use the trophy/star when clear. So you will potentially get 4 upgrades before the end of the game and you can earn up to a 5 star rating.
Shuffle full deck of cards and draw the top 45(45 minutes)
From those 45 lay out the top 8 as your market and draw the next 4 as your hand.
Objective: attain the highest star rating (trophies) as possible before the deck runs out. The game ends when you have to draw a card and the deck is empty.
No changes to the normal rules, on your turn you can do market research, use your owner card, or play a card from you hand.
I think that about covers it. I tried playing varying ways and could maxed out at 4 stars most of the time sometimes 3, but the draws have to be pretty perfect to get 5 stars.
Let me know if you have any feedback.
Just got my copy today played a few solo variants: one change I thought of that might make it easier is the game ends when the market is empty instead of last card in the deck. This really is like a twisted version of solitaire but still fun
