In Honkai: Star Rail’s thrilling Cosmic Lucky Prize event, every daily login turns into a high-stakes gamble: will you settle for a safe 100 Stellar Jades, or risk it all for a shot at a staggering 500,000 Stellar Jades-enough for over 3,000 gacha pulls? With only 20 lucky winners across the event, the choice between guaranteed rewards and life-changing jackpots could redefine your journey through the stars.
Below, we explain how the Honkai: Star Rail Cosmic Lucky Prize event works and which option you should pick to net the most Stellar Jade.
How does the Cosmic Lucky Prize work?
The Cosmic Lucky Prize in Honkai: Star Rail is a limited-time lottery event divided into seven daily phases, where players choose between a guaranteed 100 Stellar Jades or entering a prize draw for a chance to win big. Each phase offers a grand prize called the “Lucky Superstar,” awarding 500,000 Stellar Jades to a select few-20 winners total across the event. If players enter the lottery but do not become the Lucky Superstar, they have a 10% chance to win the First Prize of 600 Stellar Jades and a 90% chance to receive the Second Prize of 50 Stellar Jades. Players can only win one prize per phase and can only be the Lucky Superstar once during the event. Rewards are delivered the next day via in-game mail, making the event a high-risk, high-reward gamble versus a safer, smaller guaranteed reward option.
Every day when you log in, you will be presented with a choice: Take the 100 jades now? Or enter a lottery?
So there’s a chance every day to win 500,000 Stellar Jade from the lottery, and if you are not among the lucky few players who gets that grand prize, you’ll have a 10% chance to get 600 Stellar Jade and a 90% chance to get 50 Stellar Jade. Your reward from the lottery will be delivered via the event screen the next day. You can only win the 500,000 jades once (if you’re so lucky to even win).
There will be varying numbers of winners each day and 20 winners total.

Pretty much, the lottery is for the gamblers and the 100 Stellar Jades are for those who like to stay safe.
So, should you pick the 100 Stellar Jade or the lottery option?
When deciding between the guaranteed 100 Stellar Jade or the lottery option in Honkai: Star Rail’s Cosmic Lucky Prize event, it depends on your risk tolerance. Choosing the 100 Stellar Jade option ensures a steady, guaranteed reward each day, totaling 700 Stellar Jade over the 7-day event. On the other hand, the lottery offers a chance to win the grand prize of 500,000 Stellar Jade, but with only a 10% chance to win 600 Stellar Jade and a 90% chance to receive 50 Stellar Jade on non-grand prize days. The lottery is ideal for players who enjoy taking risks for potentially massive rewards, while the guaranteed option suits those who prefer consistent, safer gains.
Keeping it real with you, dear reader, I don’t want to be personally responsible for your gambling decisions, but I will try to advise you!
It’s safest to just grab the 100 jades daily. Picking the safe 100 Stellar Jade option will net you 700 jades over the course of the event, as opposed to the lucky prize, which will very likely just net you 350 Jades – unless you get lucky enough to hit that 10% and get 600 jades. However, if you hit the 10% chance one time, you’ll walk out with 900 jades total making it more worthwhile – but it’s all kind of dependent on if you actually hit that 10%. I can’t really speak for your own luck, here!
The option you pick can also depend on your need for Stellar Jades. Are you trying to pull in any of the gacha banners right now and you need more jades? Then you should pick the safer option and get the 700 jades. If you aren’t pulling for anyone and are still saving for future banners (with plenty of time to farm more jades), then gambling may be more enticing.
Which Cosmic Lucky Prize option offers the best chance for maximum Stellar Jade
The Cosmic Lucky Prize option that offers the best chance for the maximum Stellar Jade reward in Honkai: Star Rail is the lottery choice, where players risk their daily guaranteed 100 Stellar Jade for a chance to win the grand prize of 500,000 Stellar Jade. This grand prize is awarded to a total of 20 lucky winners across the 7-day event. If not winning the jackpot, participants still have a 10% chance to receive 600 Stellar Jade or a 90% chance to get 50 Stellar Jade each day. Choosing this option maximizes the potential payout but comes with the risk of lower rewards compared to the guaranteed 100 Stellar Jade option.
How likely am I to win the 500,000 Stellar Jade jackpot overall
The overall likelihood of winning the 500,000 Stellar Jade jackpot in Honkai: Star Rail’s Cosmic Lucky Prize event is extremely low, approximately 0.008%. This is because only 20 lucky winners will be chosen from a player base of around 25 million active participants during the entire 7-day event. Each day, the chance to win the jackpot is independent, but given the vast number of players, the odds remain minuscule for any individual player. Despite the low probability, the event also offers smaller consolation prizes with a 10% chance to win 600 Stellar Jades and a 90% chance to receive 50 Stellar Jades daily.
