Puzzles & Survival: Fast Completion Guide

Day 1: Redeem all codes. Join active alliance. Activate Fast-Build, then start HQ and prerequisite building upgrades. Use small speedups freely on prerequisite buildings. Save large speedups (8h, 24h) for HQ. Target: HQ 8 by end of Day 1. Days 2-5: Request alliance construction help every session. Level Xavis, Anahita, and Scarlett with obtained fragments. Activate Fast-Build before every build. Target: HQ 11-12 by Day 4-5. Days 6-12: Plan HQ 16 prerequisites in advance — do not rush HQ ahead of support buildings. Target: HQ 16 by Day 10-12. Days 13-21: Construction timers become multi-day. Stockpile 8h and 24h speedups. Target: HQ 20 by Day 18. Days 22-30: Final push to HQ 22. Use all remaining large speedups on HQ and direct prerequisites. Consider Builder Gear ($4.99) if resource costs are blocking. Target: HQ 22 by Day 28-30.

The guide originally noted that HQ 23+ practically requires minor spending. The most defensible early spend is the Builders and Researchers gear sets ($4.99 each) — these reduce construction and research resource costs through HQ 16 and pay for themselves in time saved. Beyond that, spending should only be considered if the offer payout clearly exceeds the purchase cost. Never spend on VIP in this game for GPT purposes — VIP provides comforts but is not a tracked milestone.

Puzzles & Survival is published by 37Games. It is a zombie-themed 4X strategy game where players build a sanctuary, train troops, and compete on a server map. The distinctive feature is an integrated match-3 puzzle minigame that grants resource bonuses. However, GPT offers track Headquarters (HQ) level exclusively — not puzzle stages. HQ upgrades are gated by prerequisite supporting buildings (Hospital, Farm, Barracks, Research Lab, etc.) that must meet minimum levels before the upgrade button activates. The economy hero stack and Fast-Build talent are the primary tools for compressing construction time and resource costs.

HQ Progression Logic: Every HQ level requires a set of supporting buildings to be at specific minimum levels before the upgrade button activates. The most commonly required buildings at mid-level are: Hospital (several hospitals may be needed), Farm/Farm Plot, Barracks (multiple), Research Lab, Radio Tower, and Wall. Always check the HQ upgrade requirements before using speedups on any building — only upgrade buildings that are currently blocking your next HQ level. HQ 5, 8, 12, 15, and 22 are milestone levels that unlock major new gameplay systems. HQ 16 unlocks the Pit for rare earth mining — this is a significant power gate. Hero System for Construction: The Economy heroes reduce construction resource costs and time. At max enhancement, they can reduce resource costs to zero, meaning you build entirely from stockpile without consuming materials. Priority order for Economy heroes: Otto (4-star, to level 71), Varvara (4-star, to level 71), Flint (3-star, to level 31-71), Chester (3-star, to level 31-71), Kento (2-star, to level 31), Xavis (2-star, to level 31). Do not over-invest in Combat heroes until offer milestones are complete. Puzzle Stages: Run puzzle stages primarily for the chest rewards they unlock. Chests can be strategically opened during events that reward resource collection, multiplying their value. Do not grind puzzle stages manually for resource scraps — the chest-opening timing strategy yields far more value.

Day 1: Redeem all active gift codes immediately. Android: Settings → Box. iOS: redeem via 37GAMES website. Join an active alliance within the first hour — construction help is critical. Set Economy talent tree and activate Fast-Build BEFORE starting any construction or research. Level economy heroes: Xavis (food/wood cost reduction), Anahita (steel/gas cost reduction + free speedup time), Scarlett (build speed). Check HQ prerequisites before upgrading anything — supporting buildings must meet requirements first. Run puzzle stages for chest rewards but do not treat them as the main progression path.

Join an active alliance immediately, keep builders busy, gather while offline, save speedups for main-building gates, and avoid combat losses unless required.
