Mega Tickets are golden tickets in AdVenture Capitalist that allow you to boost an investment by x7.77 permanently. They may only be used once on each different investment opportunity. To boost an investment, click on the golden Mega Ticket icon and select "Boost" under the investment you wish to boost. Any investment boosted with a Mega Ticket will become golden. Boosting all investments will change their color to platinum.
Mega Boosts is a tab located in the AdVentures. It allows the exchange of gold and Mega Bucks for Mega Tickets. One ticket can be obtained by spending either 20 gold, or 10 Mega Bucks. 10 Mega Tickets can be obtained at once by spending 180 gold, or 90 Mega Bucks, with 10% discount. Boosting all of the investments on a planet increases the boost to x17.77, which can be further increased to x77.77, x777.77, and x7777.77, by spending 10, 30, and 50 Mega Bucks, respectively. It also gives you the Mega Ticket Badge.
