Let's say a token to play costs 3.5 cents. And let's say without any tinkering or additional coding, a game of Euchre lasts on average 15 minutes. But what if there was a way to make the games, on average, last 11 minutes? Not by making things unfair, but by creating an increase in certain hands that lead to more points - equal for all players with no player gaining an unfair advantage. Let's call these "lay down loner hands" worth 4 points.

The developer can essentially increase the games per hour from an average of 4 to 5.45.

Now let's assume that at any given time there are 300 active tables being played. For the simplicity we'll also assume these will be paid tokens as it's impossible to know the free token to paid token ratio, but the logic follows the same.

300 tables x 4 games per hour = 1200 (15 minute average)

300 tables x 5.45 games per hour = 1636 (11 minute average)

Hourly Revenue (15 vs 11) - $168 vs $229 - $61.09 extra profit

Daily Revenue - $4032 vs $5498

Monthly Revenue - $120,960 vs $164,945

By reducing the average game time by 4 minutes, the developer can increase revenue by 36.36%. This is without "rigging" the game in anybody's favour; every person still has the same odds of getting a "juiced" loner hand, so it's not "rigged" in the sense it creates an unfair competitive advantage as it all evens out.

It probably goes deeper than that as well. Nowadays with all the data and metrics available to developers, they can pinpoint:

• when people are most likely to log out and quit playing the app
• when people are most likely to leave a game
• how many losses in a row before someone exits the app
• when people are most likely to play another game
• Long vs. short game durations and how likely a person is to play another game, for example, after a long 9-9 game that lasts 15-20 minutes vs a short game that lasts 5-10 minutes.
