Cycle drifted? Re-anchor it

The cycle doesn't lock to a weekday — if your in-game timer disagrees with this tool, set whichever event is currently active in-game below and its start date. Everything else recalculates.

Defaults: Bullseye started 22 May 2026 02:00 UTC, 7 days each. Times are UTC server time (subtract 1h for UK time during BST). Saved to your browser only.

Event details

🎰

Gacha Go

Capsule machine — keys, Golden Wrenches & blueprints.

How it works

  • Spin a capsule machine; balls fall into 4 slots with predetermined drop rates.
  • Cost: 100 💎 per single draw, 500 💎 for a 5-draw bundle.
  • 5 free attempts per day — never skip these.
  • Earned rewards: Keys (primary currency), Modification Blueprints, gift boxes, speedups, badges.
  • Key exchange tiers: 10 keys → 2 Golden Wrenches · 60 → 12 · 300 → 70 (best ratio).
  • Point milestones at 5,000 pts (wrenches + bonus) and 8,000 pts (15 wrenches + blueprint + gift voucher).
  • Unused keys carry over to the next Gacha Go event.

Strategy

Save your diamonds for the 5-bundle (better value than singles) and always bank keys for the 300-key tier — it's nearly 4× the wrench/key value of the lower exchanges. Banking 5,000+ 💎 before the event lets you push for point milestones at 5k and 8k.

🎯

Bullseye (Booty)

Spend diamonds for bullets, fire in 15-shot rounds, claim grand prizes.

How it works

  • Buy Shooting Bullets with diamonds: 100 💎 = 1 bullet.
  • Each round is 15 shots — the first 15 shots in every Regular Round are guaranteed to drop the grand prize.
  • Every round at a multiple of 5 (5, 10, 15…) is a Treasure Round with upgraded rewards.
  • Round 12 specifically awards an Armor S Box — a key F2P milestone.
  • Event caps at 500 rounds.
  • Unused bullets carry over to the next Bullseye event.

Strategy

If you're F2P, stop spending after Round 12 — the Armor S Box is the best per-bullet value and the curve after that is steep. Whales aiming for the 500-round cap should pre-bank bullets across cycles since carryover is your friend.

🎫

Lucky Discounter

Draw discount coupons (10/30/50/70/90% off). Pity at 5/9/18/32 + every 25 draws.

How it works

  • Use tickets (saved across cycles, no expiry) to draw a random discount. 1st draw is free; each subsequent draw costs 1 ticket.
  • Drawing activates a time-limited shop selling badges, speedups, shields & fuel at the drawn discount.
  • Drop rates: 10% Off 45% · 30% Off 30% · 50% Off 13% · 70% Off 8% · 90% Off 4%.
  • Guaranteed 90% Off at draws 5, 9, 18 and 32.
  • Pity counter: every 25 cumulative draws without a 90% Off triggers one. Counter resets each 90% (guaranteed or pity).
  • 17 free tickets per event; tickets carry over indefinitely.

Strategy

Save at least 9 tickets before starting to lock in two guaranteed 90% Off draws (5 and 9). For the 32-draw pity, bank across multiple cycles. At 90% Off, prioritise badges (~0.3 💎 per badge — roughly 5× better than normal). Detailed walk-through and per-cycle pity calculator on the dedicated tool page.

🎁

Lucky Chest

Open coloured chests with keys for blueprints, speedups & golden keys.

How it works

  • Coloured chests fill your depot (cap 100) from Gacha Go draws and ongoing play.
  • Each chest has a 20-minute window to be opened with Keys once active.
  • Rewards scale by chest colour — gold chests award up to ~60,000 blueprints per open.
  • Other drops: speedups, Golden Keys, modification fragments.
  • No published pity system — pure RNG.

Strategy

Stockpile chests during Gacha Go week so you arrive at Lucky Chest week with the depot near full. Always open within the 20-minute window — expiring chests is the most common mistake. Save Golden Keys for Gold chests only.

About the data

The cycle order Gacha Go → Bullseye → Lucky Discounter → Lucky Chest is the most-corroborated pattern across the Last Z community. Durations and exact start dates can vary by server and season — treat this tool as a planning aid, not gospel. The re-anchor controls above are there so you can correct any drift in 5 seconds.
