I started testing weekly casino promos specifically because I got tired of vague write-ups that never told you what you’d actually receive. The Thursday lootbox at Mirax caught my eye — a random outcome mechanic felt worth a proper look. If you want the full picture on the platform itself, check out my mirax casino full guide NZ before diving in here. This post is just about the Thursday code and whether it’s worth your time.

Lootbox Outcomes at a Glance
| Outcome | Spins | Frequency |
|---|---|---|
| Common | 45 | Most likely |
| Mid | 85 | Occasional |
| Rare | 100 | Uncommon |
Honestly, expect 45 spins most weeks. The 100-spin outcome exists, but don’t bank on it — I’ve seen it once in three months of testing.
How to Claim on Thursday
- Log in on a Thursday. The lootbox promo is only live that day — if you try Wednesday night or Friday morning, the code simply won’t work. Check your timezone too, as Mirax runs on UTC.
- Head to the cashier and deposit. You need at least the equivalent of 0.000325 BTC. In NZD that’s roughly NZ$25–30, though it shifts with the BTC rate. Crypto or fiat both work — the min deposit calculation is just pegged to BTC value.
- Go to the Bonus section or use the promo code field at checkout. Type in MYLUCKYBOX exactly — no spaces, all caps. The system is case-sensitive, so double-check before confirming.
- Open the lootbox. After the code activates, you’ll see an animation revealing your spin count — either 45, 85, or 100. Worth knowing: you can’t influence this, it’s random at the server level.
- Launch Stellar Spins and use the free spins. They’ll appear automatically in the BGaming slot. You have 3 days to use them, so don’t sit on them — expired spins are gone with no exceptions.
My Experience Running This Three Weeks
I ran the mirax casino thursday promo nz three weeks in a row to get a realistic read on outcomes. Week 1: 45 spins on Stellar Spins — the common result, no surprises. Week 2 was the outlier: 100 spins landed, which is the best outcome available, and I managed to clear wagering with about NZ$18 left in bonus balance. Week 3: back to 45 spins, as expected. Here’s the thing — two out of three weeks you’re likely in the 45-spin tier. The mid-tier (85 spins) I’ve seen just once in six separate activations total. Go in expecting the base outcome and you won’t be disappointed.
Wagering — Plain English
Winnings from the free spins carry a 40x wagering requirement. So if you win NZ$10 from your 45 spins, you need to wager NZ$400 before withdrawing. Max bet per round while clearing wagering is NZ$5 — go over that and the bonus balance can be voided. You have 5 days from activation to meet the wagering requirement. Only eligible BGaming and certain other slots contribute 100% — table games and live casino contribute 0%, so stick to pokies when clearing it.

Quick FAQ
What day does the lootbox reset?
The lootbox refreshes every Thursday. You get one activation per week — there’s no way to claim it twice in the same Thursday window, even if you make a second qualifying deposit. The reset happens at midnight UTC, so NZ players should account for the time difference when planning.
Can I stack MYLUCKYBOX with the welcome bonus?
No. The Thursday lootbox is classed as a recurring weekly bonus, and Mirax’s terms don’t allow it to run alongside the welcome package. You’d need to have completed your welcome bonus wagering before the lootbox code activates without issue. Worth checking support if you’re mid-welcome-bonus and unsure.
Do I need to deposit in BTC to use this code?
No — you can deposit in NZD or other supported currencies. The minimum deposit threshold is just calculated using BTC as a reference value (0.000325 BTC equivalent). In practice that’s around NZ$25–30. The mirax lootbox bonus code itself works regardless of how you fund the deposit.
