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.

This was always my go to just to pass time, but man I'm trying to beat unlimited mode and I can level items passed a certain point. I have Saudi Oil at 10490 but if I try to lvl it to 10491 then it freezes even though I can complete the upgrade. After my consult is done I'll just have to regen with my new bonuses but very annoying for a game I once gave 5 star

Hi Conan, the end of unlimited mode is a place few people ever reach! One thing that will probably help you is to go into the settings menu and switching to scientific notation. If that doesn't work, please contact us at

Game is great! But there is only one problem. Upgrades for gas well are alot more expensive than higher properties. Untill you fix that 4 stars. Edit: Well, after reading it it makes a lot of sense. And i kept comming back to this game over and over. Just noticed that i didnt edit my review. Thank you for response and for making this amazing piece of art! You dont need shiny graphic to make a good game! And this one is best one out there for me. Thanks again!

This is intentional, and we have a few reasons for the price discrepancy listed on the game wiki.

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.
