What Is the Waterfall?
Train Low, Upgrade Through Each Barracks
Instead of training T8 directly, train T5 cheap & fast, then upgrade through each barracks tier. Every upgrade scores the same points as fresh training!

Each step = points! 4 steps > 1 direct training
Barracks Stagger Setup
Target: One Barracks Per Tier
Keep one barracks at each tier unlock level — don't over-upgrade!

Weekly Prep Plan
MON–THU
Stockpile Phase: Train T5 troops in your Lv14 barracks. Queue batches every few hours. Let them pile up — do NOT upgrade yet.
THU Night
Final Prep: Complete all T5 queues. Check your training speedup stockpile. Stack radar missions.
FRIDAY
Execution Day: After reset + 5 min, run the full waterfall cascade with all saved training speedups. Every troop flows T5→T6→T7→T8.
SAT–SUN
Recovery: Resume normal training. Start building T5 stockpile again for next Friday.

Friday Execution: Step by Step
1
Wait 5 min after 6pm reset — points don't count during reset window.
2
Collect stacked radar missions — if you stacked Thu night, collect now for bonus pts.
3
Collect completed T5 from Barracks A (Lv 14). These were trained Mon–Thu.
4
Upgrade T5 → T6 in Barracks B (Lv 17). Use training speedups to instant-finish.
5
Upgrade T6 → T7 in Barracks C (Lv 20). Speedup again.
6
Upgrade T7 → T8 in Barracks D (Lv 24). Speedup to finish.
7
Repeat! Queue another batch of T5 upgrades and cascade again until speedups run out.
Speedup Math
Training speedups score 10 pts per minute of speedup used.
1hr speedup = 600 pts
8hr speedup = 4,800 pts
Friday 4x multiplier applies to ALL training activity. Duel Expert 2x stacks on top. Save EVERY training speedup for Friday!
Quick Reference Rules
DO
- Keep barracks staggered at different tier levels
- Train T5 all week in your lowest barracks
- Save ALL training speedups for Friday
- Use speedups to instant-finish each upgrade step
- Research Duel Expert to max (doubles all VS pts!)
- Cascade multiple batches if speedups allow
DON'T
- NEVER use training speedups outside Friday
- Don't upgrade all barracks to the same level
- Don't train T8 directly — you waste 3.3x points
- Don't collect troops before reset + 5 min
- Don't forget to queue T5 during the week
- Don't skip the cascade — every step = more points
Common Mistakes
✗
All barracks at Lv 24 — you can only train T8 directly. No waterfall possible.
✗Using speedups on Tuesday — training speedups only score on Friday (for VS Duel — they still count for Arms Race Unit Progression phase any day). Wasted for VS!
✗Forgetting to stockpile T5 — no T5 troops = nothing to cascade on Friday.
✗Collecting before reset — points earned in the 5-min window after 6pm don't count.
