## Omaze Odds of Winning: How to Calculate Probabilities

Back in January of 2019, I won an Omaze contest and took a surfing trip to Hawaii. Omaze offers some incredible opportunities, but the odds of winning are generally very small. Your probability of winning increases if you figure out the odds and enter wisely; in this article, I’ll show you **how to calculate probabilities and odds for Omaze**.

Watch the video for the calculations, plus some winning tips:

## What is Omaze?

**Omaze is a fundraising platform that connects donors to nonprofits.** The idea is, you donate a small amount of money— this can be anywhere from a few dollars to a few hundred dollars. In return, you get a certain number of entries for the contest. You can win anything from cars, to celebrity dates, cash, houses, and dream trips. These contests often get millions of entries, so your odds of winning one of these contests is, generally, very very small. But you can improve your Omaze odds of winning with a little knowledge of probability and odds.

First, **let’s take a look at how Omaze works**. Each person can only get 6,000 entries per contest. But you don’t have to enter six thousand times. You only have to enter three times, and here’s why: you can get 2,000 entries by donating $150. If you do that amount 3 times, you’ll get the maximum number of entries. In other words, donate $450, and you have 6,000 entries. Of course, you can keep on donating, but donating more than $450 prize will *not *increase your odds of winning.

I’m assuming you don’t have 450 dollars hanging around to enter contests. But **there is a way to enter without donating. **Look under the entries buttons you’ll find a “enter without contributing” option. Click that, and you’ll be taken to the Alternative Method of Entry (AMOE) page.

Fill out your info, and you’re in.

At this point, you might be wondering if you have to enter the contest 6,000 times to max out your Omaze odds of winning. The answer is no, and you can find out why in the official rules, which state:

“Upon receipt of a complete “Alternative Method of Entry” form, a Participant will automatically receive two thousand (2,000) entries into that Experience.”

In other words, **if you fill out the AMOE three times, you get the maximum number of entries.** That’s why Omaze can say everyone has an equal chance of winning; You can get that equal chance (or even give to a little bit of an advantage over people who only enter once) by maxing out your entries.

Before I get into some tips about how to increase your odds of winning, let’s take a look at how odds and probabilities are calculated.

## Calculating Probabilities and Odds for Omaze

Odds is defined as **the probability an event will happen divided by the probability that it will not happen**. In other words, it’s a ratio of successes (or wins) to losses (or failures). As an example, if you enter 100 contests and win 20 times, the odds of you winning a contest is 20/80 = 1/4. But when we have a small number of events—like one Omaze contest— odds and probabilities are almost identical, and it’s often easier to talk about probabilities instead of odds. For this contest example, the probability you’ll win is 1/5, that’s a 20% chance of a win.

So what is the Omaze odds of winning? Omaze doesn’t give us any numbers to work with.

The official rules just say that

“The odds of winning depend on the number of eligible entries received during the Entry Period.”

Why do the odds depend on the number of people entering? Let’s take a look at a quick example. I’m going to assume that everyone maxes out their 6,000 entries by either donating $450 or using that AMOE form: Let’s say you have one $100,000 prize up for grabs. You enter the contest so do four other people. There are five contestants, and you are one of them. The contest closes, and a winner is drawn randomly; You can find this info on Omaze’s blog:

“…a potential winner is randomly drawn via a cryptographically secure random number generator.”

As this is a completely random event, **everyone has an equal chance of winning**. This equal chance is important, because that small nugget of information allows us to calculate some probabilities:

- If 5 people enter (including you), your odds are 1 to 4; the probability you’ll win is 1 out of 5, that’s 20%.
- If 50 people were to enter, your odds are 1 to 49; the probability you’ll win is 1/50. That’s 2%.
- If 5,000 people enter, your odds are 1 to 4,999; your probability of a win is 1/5000. That’s .02%.

So the big question is, **how many people enter these contests? ** We need to know that, in order to figure out our Omaze odds of winning.

For that, **we need a little detective work**. Omaze doesn’t release figures for how many people entered the contest, either by donation or by that AMOE form. So let’s take a look at a couple of contests and see if we can figure out what the odds might be.

## Omaze Odds of Winning: Examples

It goes without saying that **Star Wars** is really popular, so let’s take a look at the popularity of an Omaze contest featuring Star Wars. Forbes reports that win a walk-on part in Star Wars: The Force Awakens raised a staggering $5.3 million dollars.

Next, let’s take a look at something more low key, like surfing with celebs Kelly Slater and Shane Dorian. You might have to scroll through some results before you get some relevant info, but I found what I was looking for on this site. *The Interia* reports that the surfers most recent Omaze campaign raised of $75,000. Apparently, a lot more people want to walk the red carpet than go surfing! In fact, *Star Wars raised over seventy times more money than this surfing contest*. We can safely assume that 70 times more people entered. But how many people does that equate to? We have to do a little guesswork here, as, yet again, Omaze doesn’t publish these figures.

Let’s assume 50% of people donated and 50% enter via AMOE. If we also assume that most people are pretty much broke and they are going to enter the minimum, $10, then we divide the amount raised by $10 to get some** rough numbers.** A Couple of notes about the method I’m using: in statistical analysis, if you don’t know what proportion of a population does what, then most of the time you’ll use 50%. Secondly, by using the same “guesstimate” across all contests you’re comparing, you’re making those comparisons fair.

- For a star wars part, 5.3 million dollars / 10 = 530,000 people donated. Plus 530,000 possible AMOES, so the total number of people entered is over a million people. That shouldn’t come as a surprise as a lot of people—including me—wouldn’t mind walking onto a star wars movie set!
- For surfing, let’s take Kelly Slater’s contest, which raised $75,000. Divide that by $10 per person and you get 7500 people. Doubling that to allow for AMOE entries gives us 15,000.

As probabilities, we get:

- Star Wars: 1 out of 1 million.
- Surfing trip to California: 1 out of 15,000.

If you can only enter one contest, it should be pretty obvious which one you should enter: **the surfing trip has much better odds. **And don’t forget, if you and a significant other enter, you double your Omaze odds of winning. That lowers your probabilities to

- Star Wars: 2 out of 1 million = 1 out of 500,000.
- Surfing trip to California: 2 out of 15,000 = 1 out of 7500.

This gives us a good idea about the overall Omaze odds of winning. **The probability of winning depend mostly on what kind of contest draws the most entries.**

- If the contest has an A list celebrity, your odds are going to around a million to one.
- For cars and cash, the odds are slightly better, but still very high; lots of people enter these contests, so you’re looking about 500,000 to one.
- For contests with minor celebrities, especially ones that involve physical activities like hiking, or surfing, your odds are much better. That’s because most people who enter sweepstakes are going for the luxurious lifestyle, not exercise! Depending on the contest, your odds could be as good as 2000 to one, assuming that you max out your entries and you get a friend or two to enter as well.

Back in 2018, when I won the trip to Hawaii, the rules were different: you could get a maximum of **one million entries.** In other words, you could enter 500 times back then. That made for much better odds, but if you choose your contest entries wisely, it’s still very possible for you to win. You can increase your odds dramatically if you **enter every contest you want to win**.

And remember, If you use the AMOE form, those entries are free. Your odds will still be high, but you’ve done all you can. Now’s the time to sit back, and cross your fingers.

## Omaze Odds of Winning: Summary

In order to maximize your Omaze odds of winning:

- Do a little research on past contests and Enter the contests with the highest probability of a win.
- Max out your entries.
- Use the AMOE form.
- Get your significant other and your friends to enter to double, triple, or quadruple your odds. Just make sure they agree to share the prize if you win!

Finally, if you feel a little guilty about not donating anything, **here’s how to enter an Omaze contest by donating just two dollars**—the cost of a scratch off lottery ticket. Go to the AMOE form and you’ll see a button where you can donate two dollars to enter.
