Welcome to Oil Tycoon!
To play, first buy some Gas Royalties by clicking on the Level 0 button; then click on the Gas Royalties to earn money. Your current money is displayed near the top of the screen.
Once you have enough money, you can increase the level of your Gas Royalties, or buy new properties like the Oil Royalties. Continue clicking on the property to bring in more money!
If you have a lot of money to spend, you may want to toggle buy 10x on at the bottom of the screen. This button allows you to buy ten levels at once.
Your CEOs will run the properties for you, even when the game is closed. Click the button to raise a CEO's level.
The higher the level a CEO is, the less idle time a property will have between runs, however the CEO will never be perfect, so you can still manually click on properties to make them run faster.
Next, look into the technology tab. Here you will find upgrades that let you multiply the earnings from one or all properties, just click the button to buy. It is up to you to determine when a technology upgrade is a better choice than leveling further.
You can toggle between viewing new or purchased technologies with the buttons at the bottom of the screen.
At certain milestone levels, your properties will automatically earn achievements to help you gain money. You can toggle between acquired and available achievements using the buttons at the bottom of the screen.
The stats tab will show information about your money earning rates for each property, as well as overall.
Finally, if you feel like your clicking rate has slowed down too much, you can retire. This will reset the game as you hand your experience down to your protégé. On subsequent playthroughs, the properties will produce more money at equivalent levels, and more money means more experience to start all over again!
