It was fun to run many times until reaching infinity. When running it now Android warns me it's for an older version of Android and may have issues, so I guess I am reluctant to start a new session, but I couldn't step away without saying thanks for all the Increments. :) PS I've found I can avoid the crash for longer and push things farther if I switch the default notation.

I've played this for a while now. My advice is to retire as soon as you have 10-100x your current experience. And switch to infinite mode as soon as you run out of technology, or the game will stagnate. Before I tried infinite mode it required a week for the efficiency manager to max out the Saudi field plus several consultant cycles to make any experience just to start over again. Was fun for a while but I think the infinite thing will last longer.

You can email us at It does sound like you've basically hit the max, but we can straighten it out to give you a slightly more fulfilling end if you'd like.

What's new

The Negotiator is now available under the specialists tab. This specialist will improve the price you pay for properties.

Buy 100x button added.

When all achievements have been acquired, the next retirement will prompt you to turn on unlimited mode.

Completing standard mode first is recommended, but it is always available in the settings menu.
