What is it?
An off-season celebration made of three separate systems that members constantly confuse: Confirmed Mechanic
| System | Timing | Action | Output |
|---|---|---|---|
| Bingo Task | First 7 days | Complete a fixed 15-task board + lines | Black Market Cash + final reward |
| Cash Challenge | Following three 7-day phases | Earn cash from ordinary PvE/alliance activity up to a cap | Up to 600 standard cash/day + uncapped Secret-Squad cash |
| Merchant / store | Full 28-day cycle | Refresh offers and spend currency | Items, free slots, discounts — not the earning challenge |
“Finish Bingo,” “cap the Cash Challenge,” and “claim the free Merchant item before refresh” are three different instructions — don’t blur them. {CONF}
The fifteen Bingo tasks
| # | Task | Optimization |
|---|---|---|
| 1 | Execute 8 Legendary Secret Tasks | Refresh and preserve Legendary tasks; overlaps Secret Mobile Squad. |
| 2 | Train 3,000 units | Pre-stage empty training queues; align with a training VS/Arms Race day. |
| 3 | Use 3,000 min construction speedups | Don’t spend the week before Bingo without reason. |
| 4 | Recruit heroes 30 times | Nested inside the 100-recruit task. |
| 5 | Log in 1 day | Automatic. |
| 6 | Collect 200 Alliance Gifts | Requires an active alliance; begin immediately. |
| 7 | Log in 5 days | Can’t be rushed; a missed day can block the full board. |
| 8 | Gather 2,000,000 resources | Send long marches before reset if collection counts during the event. |
| 9 | Defeat 20 Doom Elites | Use alliance rally coordination. |
| 10 | Complete 100 radar tasks | Stack radar capacity beforehand where possible. |
| 11 | Make 100 alliance donations | Use donation opportunities consistently. |
| 12 | Use 3,000 min research speedups | Align with Age of Science / research phases. |
| 13 | Help allies 200 times | Active alliance construction/research/healing makes this trivial. |
| 14 | Dispatch 10 Trade Trucks | Don’t exhaust dispatches before the event starts. |
| 15 | Recruit heroes 100 times | The 100 total also clears the 30 threshold. |
Bingo reward math
The board pays per square, per line, and for the full board: Confirmed Mechanic
| Component | Calculation | Cash |
|---|---|---|
| Task squares | 15 × 50 | 750 |
| Rows + columns | (3 + 5) × 400 | 3,200 |
| Full board | Legacy reward (your cycle) | 400 cash + 2 Survivor Recruitment Tickets |
On the Server 2132 cycle the full-board bonus pays the legacy 400 cash + 2 Survivor Recruitment Tickets, not the generic current cash bonus some guides show. Update-Sensitive Always check the visible reward preview before publishing totals — the per-square and per-line values can also differ from the example by cycle. Update-Sensitive
Cash Challenge — cap and exceptions
Standard activities pay up to 600 Black Market Cash per day. One activity may be doubled for the week — doubling reaches the cap faster but does not raise it. Confirmed Mechanic Across 21 Challenge days the standard ceiling is 12,600 cash. Secret Mobile Squad cash sits outside the cap, with Legendary tasks paying the most. Confirmed Mechanic Some later documentation says unused daily capacity rolls forward, but that’s version-sensitive — confirm in the event panel. Update-Sensitive
What should I prepare?
| Before event | Day 1–2 | Day 3–5 | Day 6–7 |
|---|---|---|---|
| Save 100 recruitment actions, 3,000 construction + 3,000 research minutes, radar capacity and trade-truck dispatches. | Open board; verify the final reward; trigger nested and speedup tasks during matching VS phases. | Track login, gifts, donations, helps, radar and Legendary-task bottlenecks. | Audit every square and line; don’t leave the 5-day login or 8 Legendary tasks incomplete. |
How do we win?
Open the Challenge page daily, identify the doubled activity and remaining cap, and do the lowest-stamina activities first — especially ones you already need for VS, Radar Day or alliance events. Stop tracking standard drops once you hit 600; keep dispatching Legendary Secret tasks because that cash is uncapped. Corroborated Strategy Preserve enough cash for Champion Duel predictions if that stage is live.
Common mistakes
- Calling all three systems “the Black Market” and doing the wrong activity.
- Spending construction/research minutes the week before Bingo opens.
- Missing a login day and blocking the full board.
- Grinding ordinary activity past the 600 cap, which adds nothing.
- Forgetting Legendary Secret tasks are the only uncapped cash source.
Leadership protocol
Use three distinct names in every announcement — “Bingo,” “Cash Challenge,” “Merchant” — so members don’t grind the wrong layer. Publish the save-list before the cycle opens, and remind members the standard cap is 600/day while Secret-Squad cash is uncapped. Leadership Protocol
The full-board reward and the daily-cap rollover are the two version-sensitive points here. Your cycle shows the legacy full-board reward (400 cash + 2 Survivor Recruitment Tickets), which differs from the generic ~1,500-cash bonus other guides print — so the visible reward preview, not a guide, controls your totals. Rollover of unused daily cap is documented in some later celebrations but not all; leave part of one day’s cap unused and compare the next day to test it on 2132 before assuming you can bank capacity. Everything else — the 15 tasks, the 600/day standard cap, the uncapped Secret-Squad cash — is solid.
