Clockwork Roulette — Jackpot service. 7-cog full send = 56 total vouchers (7 normal + 49 bonus), the biggest single payout in the minigame.

Activation-first N×N: activate all cogs first, THEN complete them. Each completion pays out based on activated cog count, not completed count. Clearing as you go loses most of the bonus.

Full-send or reroll. Every activation rolls a 9% brick check. 7-cog survival ≈ 52%. Stopping partway throws away the escalating bonus while still eating the brick risk.
