Gossip Harbor®: Merge & Story Stadium Defense Event Guide

To complete the Stadium Defense event in Gossip Harbor®: Merge & Story, fulfill high-tier customer orders on your main board to earn event progression points and clear milestone tiers before the event timer runs out. Focus your energy pool on finishing one major order at a time rather than splitting generator taps across multiple merge lines.

How Stadium Defense Progression Works

Stadium Defense functions as a milestone ladder where turning in main board orders generates defense points. Submitting completed customer requests fills a progress bar that moves through consecutive defensive checkpoints.

Key progression mechanics include:

Wave Milestones: Each cleared milestone unlocks an interim reward box and advances the defense bar toward 100% completion.
Point Scaling: Point thresholds remain low during early waves, but the point requirements increase sharply across the final third of the event track.
Active Turn-ins: Progress requires submitting active customer orders; passive merging without order fulfillment does not award event points.

Milestone Completion Rewards

Reaching the final milestone wave awards a grand prize package alongside the accumulated milestone chests:

Top-Tier Card Packs: Grants rare cards targeted toward completing 4-star and 5-star seasonal album sets.
Large Energy Chests: Supplies bulk energy reserves to replenish pools spent during order fulfillment.
Gems: Provides premium currency to recover resources spent on daily energy refreshes.
Production Boosters: Awards utility items including scissors, time skips, and generator components.

Order Priority and Board Management

Not all board requests yield the same point efficiency per unit of energy. Use the following breakdown to determine which orders to prioritize on your merge grid:

Order Type	Board Footprint	Point Efficiency	Recommended Action
High-Tier Single Items	Low	High	Prioritize during full energy pools.
Multi-Item Mid-Tier Sets	Medium to High	Moderate	Clear steadily to open grid space.
Low-Tier Quick Requests	Low	Low to Moderate	Use to spend remaining, odd energy amounts.
Secondary Generator Drops	High	Variable	Complete only if required by an active order.

To keep production moving smoothly:

Target one generator line at a time. Spreading taps across unrelated chains—such as bakery, seafood, and coffee—clutters the board with incomplete items and slows point generation.
Clear byproduct tiles. Sell off unnecessary low-tier secondary drops to maintain open workspace around your primary generators.
Open banked energy boxes. Open stored inventory energy crates exclusively while the event is live so that every stamina point directly fuels event milestones.

When to Push for the Final Wave

Because the final tiers require substantial item commitments, evaluate your current inventory before committing to a full clear:

Push for completion if your seasonal card album has missing 4-star or 5-star cards and you hold surplus gems or stored energy boxes. The combined reward package and album completion payouts can offset the high energy expenditure.
Stop at the nearest milestone if you enter the final 24 hours in the lower-middle tiers without reserve energy or gems. Ending at your current checkpoint lets you bank resources for the next event cycle without starving standard story orders.
