Roadman: Revenue and Readies

One move is to drop the coin on the police to reduce their stars (suspicion level). They simply disappear, with your coin.

Here is another move, to recoup that coin:

To completion, it takes about 30 minutes.

Strategy

There are a lot of buttons, and mobile players are disadvantaged in being unable to hover:

Expand	Increases width/number of lanes in your road/pipeline.
Intensify	Increases number of horizontal locations in your pipeline/road.
MoreWeapons	Increases the likelihood of weapons appearing, this is just a probability. It make knives (level 2 weapons) 10-15% more likely, then scales to better levels and higher prices.
BetterWeapons	Simple +1 damage to all weapons. Perhaps if sold separately for each weapon (each is a level) it could be more affordable, and more “micro”.
DefenceBarrister	Resets your incrimination bar.
FixHealth	Resets your health bar.
Profit	Increases the number of coins you bank when they reach your ends.
Networking	Increases the frequency of users coming to score, by a very similar proportion as “More Weapons” does. i.e. 10-15% for level 2s then scaling up and getting more expensive.
TakeContract	Purges a whole column of enemies. The right-most column containing roadmen.
DonateToPolice	Reduces your incrimination slightly, and removes the nearest column of police.
PushySelling	Increases the base likelihood of upselling a higher quantity (level) to a lower level user. Base chance is 5% per level difference. This adds 3% plus an amount proportional to the level of the powerup purchased.
Investment	Increases likelihood of coins appearing in your road. By 10-15% for higher value ones, and scaling with successive upgrades.
LawyerUp	Increases the amount of evidence police require to prosecute you.

The Sliders

The formula is that the slider value (going from 0 to whatever is displayed at the top) is divided by 100.0, added to 1.0, and multiplied by the weight of that drug, or addict, appearing, which are typically, but not necessarily rated at 0-1.0 by default (it varies over time). All weights are relative, so you have to know the weights for all the other items, which vary as the game progresses.

I tested this, for 100 turns using "the algorithm". With the slider turned maxed out, cannabis appeared 53 times. With the slider all the way down, it only appeared 38 times.
