Absolutely – you can change the think time using the “Settings” modal. To get there, on the Mobile website, tap the “Settings” link, and on the desktop website, click the blue gear icon above the Calculate button.

Keep in mind, though, that shorter think times often produce weaker moves: the more time the engine has to search for a move, the more likely it is to find a stronger one.
