For some reason you get less idols doing a mobile reset than resetting on kong or armor games. I only found out because I couldnt get the ads to work on the web version. We think it might be due to a calculation error for Idols over time. This was on an overnight run to area 956.
Armor games would give 7827 without ad bonus and 9785 with ad bonus.
Kongregate would give 7844 without ad bonus and 9806 with ad bonus.
Mobile reset would give 6888 without ad bonus and only 8610 with the ad bonus.

The time on kongregate was about 7 hours and 40 minutes when I looked, and the time played when I looked at the mobile reset was about 7 hours and 42 minutes, so it should have been a bit higher than the kong idol gains.

When I finally did reset on the web version I got 9869 Idols for playing 7 hours 46 minutes and 33 seconds.
