For inexperienced players, ranking may be difficult, but after time, people can develop strategies to become more efficient with their time and resources. This allows players to get the 3-4m points daily, earn a few dozen keys, and do lots of EH without spending cash, lots of hours of grinding, or a bunch of resources. Ranking then becomes easy once they figure out the right strategies.

However,  no, it won't be done by playing 10 minutes a day. But ten or so minutes every few hours can do the trick if you know what you're  doing. That should be casual enough to do on the regular and maintain t1k.
