Talk:The Gauntlet (Season 9)/@comment-26829117-20161025124622

Just for the record, here is how I completed this challenge:
 * Kicked off first level updates and started running. Reached Boss level 5 before upgrades completed (watched a lot of adverts). Kicked off second level R$ upgrades. Carried on running to boss level 6 and decided not to try for boss level 7 despite it looking reasonably easy.
 * Ran to boss level 6 again with second run. Second level upgrades not kicked in yet so decided to restart again
 * Ran to boss level 5 and it was getting harder so decided to restart and not try for boss level 6
 * Ran to boss level 5, felt easier than previous run because of challenges that were presented
 * Ran to boss level 3 - car in garage.

So five runs, 66553, R$ only upgrades, lots of adverts. Started about 6am and finished at 1am (wasn't running continuously, had lots of other things to do).

I had to reset my Ad ID several times to keep the ads coming. I tended to only use two ads on servicing leaving about an hour to go. This gave me time to do the qualifying levels and then a bit of a break before the boss car was ready again. It's easily doable with this strategy within 24 hours and without spending a penny of gold.
