Event Overview: What You Need to Know
Bing-Bang Finchball transforms Genshin's combat gameplay into physics-based pinball set in Natlan's Collective of Plenty tribe. This tests timing precision and stage mechanics rather than character builds or artifacts.
Event Duration: December 5, 2025 (10:00 server time) - December 15, 2025 (03:59)
Stage Unlocks:
- Stage 1: December 5
- Stage 3: December 6
- Stage 5: December 7
- Stage 7: December 8
Each unlock grants access to two consecutive stages after clearing previous ones.
Requirements:
- Adventure Rank 20+
- Archon Quest Prologue Act 3: Song of the Dragon and Freedom
- Optional: Archon Quest Chapter V Act V (adds Natlan context)
These minimal requirements make this one of the most accessible primogem sources. For players maximizing reserves, Genshin Impact primogems top up offers competitive rates through BitTopup's secure platform.
Total Rewards Breakdown
- Primogems: 400-420 total
- Hero's Wit: 4-10 experience books
- Mora: 240,000
- Talent Books: 6 each (Guide to Contention, Kindling, Conflict)
- Sanctifying Unction: 6 units
- Mystic Enhancement Ore: 24 units
- Furnishing Blueprints: 3 unique decorations
Each stage has three reward tiers based on score thresholds. Stage 1 requires 1,000/1,200/1,500 points, rewarding 30 Primogems + 2 Hero's Wit (tier 1), 20 Primogems + 3 Guide to Contention (tier 2), and 30,000 Mora + 3 Mystic Enhancement Ore (tier 3). Pattern scales across all eight stages.
Scoring System Mechanics
Launch the Finchball using the Launch Button, then control left/right flippers to rebound and prevent falling. Every object hit generates points—moving opponents like gulls yield substantially higher scores than static targets.
Key Scoring Principles:
- Shameless Gulls, Chagrined Bandit Gulls, Glutton Mountain Weasel = high value
- Stationary objects = minimal points
- Stage-specific Finch Techniques = massive score amplification
- Chain techniques with multi-target hits for max efficiency
Stage-Specific Mechanics
Stages 1-2: Foundation
- Stage 1: Finch Technique enlarges ball, pierces multiple enemies
- Stage 2: Flamegranates deal AoE damage, eliminate nearby gulls simultaneously
Stages 3-4: Complexity increase
- Stage 3: Shielded gulls need two hits; Double Trouble spawns two balls for 10 seconds; explosive barrels add AoE
- Stage 4: Chaotic Wooden Boxes contain random rewards (barrels, extra balls, Flamegranates, or gulls)
Stages 5-6: Specialized techniques
- Stage 5: Fiery Fireball rains across board, removes shields from Chagrined Bandit Gulls
- Stage 6: Portal of Prizes transports ball to timed coin bonus stage
Stages 7-8: Boss challenges
- Stage 7: Glutton Mountain Weasel with destructible shield; flipping doubles point values
- Stage 8: Lead Secret Source Cores to Flamegranates for massive explosions
Stage-by-Stage Walkthrough
Beginner Stages (1-3)
Stage 1 (1,000/1,200/1,500 points): Activate Finch Technique by bouncing off gulls. Once enlarged, pierce through clustered enemies. 1,500 demands consistent technique activation and multi-target hits.
Stage 2 (1,000/2,000/3,000 points): Flamegranates respawn periodically—hit when gulls cluster nearby. Single well-timed explosion eliminates 3-5 gulls (500+ points). Reaching 3,000 requires 2-3 optimal Flamegranate hits.
Stage 3 (1,000/3,000/5,000 points): Activate Double Trouble early to maintain two balls, doubling damage output. Hit explosive barrels when both balls active. 5,000-point threshold needs 60%+ Double Trouble uptime.
Intermediate Stages (4-6)
Stage 4 (2,000/4,000/6,000 points): Boxes near flipper zones are safer to open. Prioritize upper playfield boxes when ball has high momentum. For efficient primogem supplementation, buy cheap Genshin primos through BitTopup with instant delivery.
Stage 5 (2,000/5,000/8,000 points): Time Fiery Fireball when gulls spread across board. Chagrined Bandit Gulls move in predictable patterns—position ball for interception after shield removal.
Stage 6 (2,000/5,000/8,000 points): Portal appears in fixed locations. Inside bonus stage, hit high-value coin clusters in center rather than chasing edges. Single successful portal run = 1,500-2,000 points toward 8,000 objective.
Advanced Stages (7-8)
Stage 7 (5,000/7,500/10,000 points): Weasel's shield needs 8-12 hits. Once flipped, ignore gulls and focus on boss for doubled points. 10,000 requires flipping weasel twice minimum.
Stage 8 (5,000/7,500/10,000 points): Secret Source Cores emerge from burrowed weasel. Intercept and redirect toward Flamegranates. Explosion deals massive damage (2,000+ points per detonation). 10,000 requires three successful combos plus consistent gull elimination.
Common Mistakes to Avoid
Passive Play: Defensive strategy fails in stages 5-8. Single Flamegranate explosion (5 gulls) > 30 seconds random bouncing.
Hoarding Techniques: Techniques recharge quickly. Activate immediately upon availability rather than waiting for perfect moments.
Ignoring Tier Breakpoints: Primogems heavily favor first two tiers. Stage 1 awards 30, 20, 0 primogems respectively—third tier gives only Mora/ore. Prioritize second tier across all stages (400 primogems) over perfecting individual stages.
Premature Flipper Activation: Wait until ball is within one character-width before activating. Generates powerful horizontal trajectories vs. weak vertical bounces.
Advanced Tips
Physics Exploitation
- Flipper outer edge = sharper angles for precise targeting
- Flipper inner edge = gentler angles for multi-bounce combos
- Activate during downward arc = add velocity
- Activate during upward movement = reduce speed
Hidden Mechanics
Explosive Barrels: Blast radius varies with ball velocity. High-momentum hits = larger explosions affecting more gulls.
Glutton Mountain Weasel: Hidden vulnerability window (3 seconds after flipping) = triple points instead of double. Golden flash visual cue. Concentrate hits during this window for 1,500+ points per flip cycle.
Mobile Adjustments
Touch control delay averages 50-80ms vs. PC's instant input. Activate flippers based on ball position one bounce earlier to compensate for lag. Use audio cues—each gull elimination has distinct sound—to confirm hits without visual tracking.
Time-Efficient Completion Schedule
Complete in 90-125 minutes total:
Day 1 (Dec 5): Stages 1-2 (15-20 min, 120 primogems). Talk to Basima the Fifth to begin (5 min intro quest).
Day 2 (Dec 6): Stages 3-4 (25-30 min). Budget extra attempts for Stage 3's 5,000-point spike. Stage 4 RNG may need 2-3 runs.
Day 3 (Dec 7): Stages 5-6 (30-35 min). Run Stage 6 once for exploration before attempting 8,000-point objective. Portal layout stays consistent.
Day 4 (Dec 8): Stages 7-8 (35-40 min). Watch Stage 8 mechanic demonstration twice before serious runs.
Alternatively, complete 1-2 stages daily across full 10-day duration without losing rewards.
Resource Value Analysis
240,000 Mora: Covers ~60% of single character's level 80-90 ascension.
18 Talent Books: Represents 3-4 days domain farming.
6 Sanctifying Unction: Saves two weeks weekly boss farming for Natlan weapon ascension (Mavuika, Xilonen, Citlali).
24 Mystic Enhancement Ore: 28,800 weapon XP—levels 4-star weapon 1-50 or contributes 40% to 5-star's 1-90 journey.
3 Furnishing Blueprints: Unique Natlan housing decorations, contribute to trust rank progression.
Event Comparison
Bing-Bang Finchball equalizes player power—AR20 newcomer has identical scoring potential as veteran with built teams. No character builds or artifacts required.
Primogem Value: 400-420 primogems = mid-tier generosity. Spiral Abyss offers 600 but demands character investment. Login events give 300-400 for minimal effort.
Time Investment: 90-120 min total vs. Theater Mechanicus's 3-4 hours. Better primogem-per-hour ratio.
Accessibility: Skill-based mechanics allow any AR20+ player to claim full rewards through practice vs. gacha luck or resource investment.
FAQ
How many Primogems total? 400-420 Primogems across eight stages. Reaching second tier in all stages guarantees 400; perfect completion yields 420.
Minimum Adventure Rank? AR20 + Archon Quest Prologue Act 3. Chapter V Act V optional but recommended.
Event duration? December 5, 2025 (10:00) - December 15, 2025 (03:59). 10 days total with progressive unlocks.
Need Natlan characters? No. Skill-based minigame doesn't use character roster. Success depends on flipper timing and mechanics, not builds/artifacts/teams.
Hardest stages? Stages 7-8. Stage 7 requires weasel shield destruction and flip timing mastery. Stage 8 demands precise Core manipulation for Flamegranate explosions. Both have 10,000-point top tiers.
Completion time? 90-125 minutes total across four-day unlock schedule. Individual stages: 10-15 min (early) to 20-25 min (Stages 7-8 with practice). Extend across 10 days at 1-2 stages daily without penalty.
