Some games are more complex than others and thus are inherently more time consuming. If you're working very efficiently, you might be able to handle a simple game in as little as 5 or 6 minutes. However, most test-takers require at least 7 or 8 minutes for even the simplest of games. Complex games may realistically call for as much as a 10-minute investment of your time. A slow pace is generally inefficient, even for challenging games.
Logic games are easier for some test-takers than for others.
