Research options

Click a bubble to change it's color to red, yellow or green. You can't change blue bubbles. Green means it's available right from the start. Yellow means you have to research it in-game and red means you'll never be able to build it in your scenario.Instead of changing them all manually you can just click the random or enable all buttons. Click the buttons left of random to change if it applies to all pages, or the current page only. Read the tooltip at the bottom-left of the window to see what each button does or what the current state of an item is.Click the x/x/x of an item to go to the ride improvements.If you decide to do it all manually, I'd advise you to make sure there are no researchable ride-improvements or disabled attractions. This makes it easier to change the sequence.Sequence tab - Left you can choose the category of which you want to change the research sequense. Click an attraction the then 'Move Up' or 'Move Down' to change the sequence. Attractions at the top of the lists will be researched first. Or simply click the Randomize button.
