The hot events are four diamond-spend events on a 28-day rotation, seven days each, in a fixed order: Gacha Go, then Bullseye Booty, then Lucky Discounter, then Lucky Choice Chest, with the switch every Friday, and the one worth saving diamonds for is Lucky Discounter, where a guaranteed 90% discount buys badges at a fifth of the VIP shop’s price.
- Scope: solo, all four
- When: each runs seven days, in that order, round and round; servers sit at different points in the cycle
- What you spend: diamonds, plus the free draws, bullets and coupons each event hands out
- What carries over: Gacha Go keys, Bullseye bullets and Lucky Discounter coupons all keep between runs
- The order to fund: Lucky Discounter first, Gacha Go for wrenches if there’s spare, the other two on their free attempts
What the hot events are and when they run
Four events share one slot on the events screen and take turns, seven days each, so each one comes round every 28 days. The order is Gacha Go, Bullseye Booty, Lucky Discounter, Lucky Choice Chest. The in-game events list shows which one your server is on; different servers started at different points.
They’re the diamond events. Each one sells its own currency for diamonds, gives a little of it free, and pays on a ladder. What makes them a set is that all three carry-over currencies keep from one run to the next, so the game rewards banking: hold the free attempts across runs, then spend them where they’re guaranteed to land.
How each hot event works
| Event | What you buy | Free each run | The guarantee |
|---|---|---|---|
| Gacha Go | Draws at 100 diamonds (500 for five); balls land in four slots and drop keys or chests | 5 draws a day | None; keys exchange on fixed tiers |
| Bullseye Booty | Bullets at 100 diamonds; 15 shots a round, a chosen grand prize per round | Bullets from daily tasks and packs | The first 15 shots of each regular round drop the round’s grand prize |
| Lucky Discounter | Coupons; each draw rolls a shop discount from 10% to 90%, the shop opens at that price for two hours | First draw free, then 2 a day from tasks and 2 from the event shop | 90% off on draws 5, 9, 18 and 32 |
| Lucky Choice Chest | Draws at 800 diamonds on a theme you pick for the week | About one a day, 7 a run | The Grand Prize at 0.5% a draw, guaranteed by draw 120 |
Gacha Go. Chests go to a depot (100 max) and each has to be opened with keys inside 20 minutes; a full depot stops new chests. Keys exchange for Golden Wrenches on tiers: 10 keys for 2 wrenches, 60 for 12, 300 for 70, 500 for 120, with daily caps on each tier. Point milestones at 5,000 and 8,000 pay more wrenches. Across a full run the wrench costs around 410 diamonds, against 300 in the VIP shop, so it’s a wrench source only when the VIP shop’s ten a week are gone.
Bullseye Booty. Every fifth round is a Treasure Round, and the reward track pays chests at rounds 3, 5, 12, 20, 50 and 200; the round-12 chest holds an Orange Equipment Choice Box, 300 Power Cores and resource chests. Round progress resets at the end of the event; bullets don’t. Reaching round 12 takes in the region of 140 to 150 bullets, which is a plan, not a promise.
Lucky Discounter. The discount odds the game states are 90% at 4%, 70% at 8%, 50% at 13%, 30% at 30%, 10% at 45%, with the 90% guaranteed on the 5th, 9th, 18th and 32nd draw. Each draw restocks the shop. At 90% off, 1,500 badges cost 450 diamonds, 1,000 badges 300, 30 one-hour construction speedups 360, ten fuel cans 100. Personal point milestones pay badges on top: 200 at 30,000 points, 1,000 at 120,000, 2,500 at 250,000, 14,000 at 750,000.
Lucky Choice Chest. Pick a theme for the week (hero fragments, exclusive equipment fragments, skill books, vehicle parts or badges) and it’s locked. The wheel on the hero theme pays Universal Orange Hero Fragments on most of its slots, with 40 of them as the 0.5% Grand Prize, and milestone chests at 10, 20, 40, 100, 250 and 500 draws. A run to the guarantee at 120 draws is 96,000 diamonds, 90,400 after the free ones.
What to do with each hot event
- Bank the free currencies across runs. Coupons, bullets and keys all carry over. The free coupons alone, about 17 a run, reach the 9th-draw guarantee in one run and the 18th in two.
- Lucky Discounter: spend on the guaranteed draws only. Draw 5, draw 9, draw 18, draw 32. At 90% off buy badges first, then speedups; skip the shop entirely at 10% and 30%. A full 32-draw run is about 30,000 diamonds for around 42,000 badges and 200 hours of speedups.
- Gacha Go: take the five free draws every day, keep the depot under 100, and bank keys for the 300 or 500 tier. Buy draws only if the wrenches are needed and the VIP shop is empty.
- Bullseye: finish the daily tasks for free bullets, hold them, and spend diamonds only to close a short gap to round 12. Past round 12, stop; the next chest is round 20.
- Lucky Choice Chest: take the seven free draws on the hero theme and stop. If you’re spending, decide the ceiling before the first draw, 40 or 120, and stop the moment the Grand Prize lands.
- Keep the shield reserve. None of this is worth an unshielded Saturday.
Hot event rewards and what to spend them on
The badges from Lucky Discounter go into Alliance Recognition, which doubles every Alliance Duel rate and is the single best thing a free account can buy with diamonds. The wrenches from Gacha Go are Monday’s Mod Vehicle Boost. The Power Cores and the orange equipment box from Bullseye’s round 12 are Thursday’s Hero Progression and a gear slot. The fragments from Lucky Choice Chest go to whichever hero the tier list puts next to star. The speedups are the Full Preparedness windows.
The reserve itself is the diamond guide‘s subject; the hot events are the second call on diamonds after shields, and Lucky Discounter is the one that justifies the call.
Mistakes that cost diamonds in the hot events
- Spending in Lucky Discounter before a 90%. Draw 4 at 30% off is full price with extra steps. Wait for draw 5.
- Stopping at draw 16 or 17. The 18th is guaranteed. One more coupon.
- Buying wood or food at any discount. The shop’s value is badges and speedups.
- Buying Gacha Go draws while the VIP shop still has wrenches. 410 a wrench against 300.
- Letting the depot fill. New chests stop arriving at 100, and an unopened chest dies at 20 minutes.
- Chasing round 20 in Bullseye. Round 12 is the box; the rest is for spenders.
- “One more” after a Lucky Choice Chest Grand Prize. The counter resets. The next guarantee is 240 draws away.
- Quitting at draw 110. The guarantee is 120. Either stop at 40 or go to 120; the stretch between is the expensive part.
Are the hot events worth it for a free player?
One of them, yes. Lucky Discounter on its free coupons is the best badge price in the game, and 17 coupons a run with the carry-over means a free account reaches a guaranteed 90% every run and the deeper guarantees every second one. The other three on their free attempts are a few wrenches, a few bullets toward a box, and seven spins at an orange fragment: worth taking, not worth funding.
The honest limit is the 28 days. Each event comes once a month, so the coupons and keys and bullets you don’t spend this week are the start of next month’s run, and a free account’s hot-event plan is mostly a bank account.
The hot events sit in the events schedule as the rotating diamond slot, and the beginner’s progression guide covers what to build before any of this matters.
