Treasure of Machines
The May-Day lottery, built on a two-stage pool. Power Cores roll the supply pool: 7 slots, no repeats, one of them the Mecha Gem that fires a core-pool roll and hands over every supply slot still unopened. The core pool is another 7 slots, three of them pick-your-own chests headed by the grand prize. Around it: cumulative-draw milestones, daily boxes, 50 quests, an Energy Crystal shop, a battle pass and a daily server ranking. The run's headline reward is the super robot Commander: Silver Wolf.
How it works
The draw runs on two levels. Every roll paid in Power Core opens a supply-pool slot — 7 slots per round, no repeats. One of them is the Mecha-Gem: it fires a core-pool roll and hands over every supply slot still unopened, then the round restarts. The core pool is another 7 slots, three of them pick-your-own rewards.
Averages are derived from the pity tables — the expected spend, not the best case.
Headline reward
The run's showcase: the super robot plus the three items the in-game pop-up advertises.
Roll cost
The price scales with how many core-pool slots are already open this round: 1 to 3 Power Core per roll, 17 across the whole ladder. Clearing the core pool costs 85 Power Core on average, because each of its slots only opens through a Mecha Gem.
Supply pool
A guaranteed reward on every roll, no repeats inside a round. Payouts grow with the number of rounds already played — switch the bands below. The Mecha-Gem slot is highlighted in gold.
| Slot | Reward | Chance |
|---|---|---|
| 1 |  Mecha-GemObtaining a Mecha-Gem triggers a draw from the Core Pool. | 10% |
| 2 | Custom Robot Fragment ×1 | 18% |

| 5 | Surprise Treasure of Machines (Mythic) ×1 | 14% |

The chance of hitting the Mecha-Gem climbs with every slot opened in the round; on the seventh it is guaranteed.
Core pool
Seven slots, no repeats. The top three are pick-your-own: you choose the item from a list, each with its own claim cap for the event. The pool refreshes once every slot is taken; if the grand prize lands early you can reset it by hand.
