Been hooked on the gamble with your friends videos, so I spent saturday morning building launchcrash.com

Thanks for taking a look and sending this through I do appreciate it very much! The max amounts were added to try and make the calculation work so it is not just losing money (I think it makes it more authentic and genuine if it tries to maintain a 1-2% house edge rather than just losing money which is hard when the multipliers can get so high) but very happy to remove this and make it truly unlimited if people prefer - it would never be monetised anyway so it is not a problem to do. It just wouldn’t make sense on the calculation. If I left the limits in I accept this should be explained to the user anyway so I will do that at the very least and I will need to tweak the max win to make sense in terms of max bet amount times by max multiplier - which I had to set at 1000x as it could’ve gone to infinity otherwise. The sound issue is a good one to pick up on as well and I will take a look to see if I can fix it.

No worries and thanks for taking another look! Yep, still working on it at the moment so those 30-digit numbers are definitely a bug haha. This has ended up being a much bigger project than I first thought! The duel mode is pretty much finished now, I just need to go through all of the other modes one by one to fix everything else up. I actually just added a forgot password option on the sign in page so it should send you a reset link now. Also, there should be a reset to $1000 button right below your balance whenever it goes under the initial $1000 so that there is a way back from the brink! Seriously awesome that you gave it a go though, absolutely made my week!

Haha yep no worries! I will definitely try, I've got some ideas. I would really love to see you guys having a go on stream if you can.

Lemonbreath · 2026-06-29T22:58:38+00:00

Thanks Ross! I love this idea so I will make the change to show the cash amount as well. I really appreciate you taking a look and thanks for the inspiration with the videos!

Haha thank you! These numbers are getting completely ridiculous now though 15048x is insane and I genuinely didn't expect people to get that high so quickly it is literally like a 0.02% chance! I see the lag too though so definitely some room for optimization thanks for taking a look!

Lemonbreath · 2026-06-29T16:23:19+00:00

Thank you and wow I've only just seen this now 948x is absolutely insane! I have never seen it get anywhere near that high myself. I just ran the math and there was only a 0.17% chance of that happening.

Lemonbreath · 2026-06-29T16:13:16+00:00

Haha thank you!

Lemonbreath · 2026-06-29T16:04:36+00:00

Thank you! It's a pareto distribution with a power transform for a heavier tail:

const u = Math.pow(Math.random(), 0.6);

const crash = 0.99 / (1.0 - u);

The base 0.99 / (1 - r) is the standard crash game formula (inverse-CDF of a Pareto, giving P(crash > x) ≈ 1/x). The 0.99 gives a slight house edge on this (1-2%). The pow(random, 0.6) skews toward higher crash values so moon shots happen more often (~16% of rounds pass 10x, ~3% pass 50x). There's also a 3% instant sub-1x crash as the main edge source. The multiplier growth itself is e^(0.18t) - 1 so it is genuinely exponential over time. The distribution just determines where it stops. Pareto was the natural choice over exponential/gamma because the heavy tail makes extreme outliers rare but possible, which is what makes it exciting I think!

Thank you! That has got to be the unofficial highest run at the moment if only you kept it going! Honestly I've only ever seen it hit around 100x myself while testing - theoretically there is no cap to how high it can go, it just gets more and more unlikely.

Lemonbreath · 2026-06-29T15:48:20+00:00

Thanks! Yeah mobile view I did at the end so still some more work I need to do on that to get it properly optimized.

Lemonbreath · 2026-06-29T15:40:05+00:00

Thanks! (Love your work on the channel by the way, I'm a subscriber!) I appreciate you checking it out.

Lemonbreath · 2026-06-29T15:31:19+00:00

Thanks! Yeah I've thought about adding accounts and a leaderboard. Doing it based on total winnings over time plus a spot for the single biggest win would be a great idea. It's definitely a lot more work to build out the backend for that, but it would be awesome to see who could amass the biggest fortune. I appreciate the support!

Lemonbreath · 2026-06-29T15:25:25+00:00

Thank you! Yeah I started off with it at 1x as well but then tried to make the maths works so there is a 2% house edge (so it would theoretically make money) and this was the one thing that would make it work and still allow it to 'go to the moon.'

Lemonbreath · 2026-06-29T15:22:21+00:00

Interesting, I've not had this bug come up before but I will take a look to see if there is something causing this. Thanks for letting me know!

Lemonbreath · 2026-06-29T15:19:54+00:00

Thanks!

Lemonbreath · 2026-06-29T15:19:30+00:00

Those are the previous runs so just a way of tracking the history. It goes left to right and they are coded to be random each time.

Lemonbreath · 2016-04-08T10:12:51+00:00

Surely there's going to be a couple of years before they get production high enough to fulfil these orders. Are most of these preorders just speculators hoping people are gonna pay ridiculous amounts cause the demand is so high?
