How long does it take to reach HQ 18 in Puzzles & Survival?
Reaching Sanctuary HQ 18 takes approximately 10 to 14 days of casual play (about 1 to 2 hours per day) if you join an active alliance and utilize your second builder queue continuously.
Can I complete the Puzzles & Survival offer completely free-to-play?
Yes. Reaching HQ 11, HQ 16, and HQ 18 is 100% free-to-play achievable within the 30-day window without spending any real money. HQ 22 is also achievable for F2P players who actively join Zombie Lair rallies daily.
Does Puzzles & Survival pend a level early on InboxDollars?
Many grinders report that milestones pend 1 level early (e.g. HQ 18 pending when hitting HQ 17). However, you should never rely on early pending; always plan to reach the exact stated level before the 30-day timer expires.
What is the single best purchase in Puzzles & Survival for offerwalls?
The 3-Star Builder Gear Set ($4.99) is universally regarded as the best investment because it permanently reduces the food, wood, steel, and gas requirements for all building upgrades by up to 25%.
What should I do if my milestone does not track on InboxDollars?
Allow up to 24–48 hours for server verification. If the milestone remains uncredited, submit a support ticket with your in-game Commander ID screenshot and building level confirmation using our included support template.
Can I play Puzzles & Survival on an emulator like BlueStacks?
No. InboxDollars strictly requires tracking on physical mobile devices (iOS or Android). Emulators almost always cause automatic tracking failure and risk account deactivation for suspected proxy fraud.
Should I push for HQ 26 or cash out at HQ 22?
We strongly recommend cashing out at HQ 22. HQ 26 requires over 120 million in gas and steel resources and weeks of build time, which makes it unprofitable for offerwall grinders.
