Introduction
Slot Bingo appears to be a pick-15 keno game. The game is made by SmartSoft Gaming, a provider of games for Internet casinos. As I show below, the game does not follow the natural odds of a fair keno.
After confronting SmartSoft with my analysis, they quickly removed the game.
Rules
- The player may play 1 to 8 cards at a time.
- Each card is marked with 15 random numbers, without replacement, from 1 to 80. The player may not choose his own numbers. The cards change after every game.
- After a bet is made, the game will draw 20 random balls, numbered 1 to 80, without replacement.
- If a ball drawn by the game matches a number on any card played, then it is marked on the card and it known as a 'catch.'
- Each card wins according to the number of catches and the pay table below.

The lower right cell shows an expected return of 772%!
Experiment
A return of 772% seemed too good to be true, so I played the free game at the SmartSoft web site. I found the average number of catches to be ridiculously low. So I recorded 20 consecutive games for more careful analysis. The following video shows those 20 games.
The next table shows the number of catches on each card in each game.
Total Catches by Game and Card
| Game | Card 1 | Card 2 | Card 3 | Card 4 | Card 5 | Card 6 | Card 7 | Card 8 | Total |
|---|---|---|---|---|---|---|---|---|---|
| 1 | 1 | 3 | 2 | 1 | 1 | 1 | 2 | 2 | 13 |
| 2 | 1 | 2 | 0 | 2 | 1 | 3 | 2 | 1 | 12 |
| 3 | 1 | 0 | 2 | 0 | 1 | 0 | 3 | 1 | 8 |
| 4 | 2 | 2 | 1 | 0 | 1 | 1 | 2 | 1 | 10 |
| 5 | 2 | 0 | 1 | 2 | 2 | 0 | 1 | 0 | 8 |
| 6 | 1 | 0 | 0 | 1 | 2 | 1 | 3 | 1 | 9 |
| 7 | 1 | 0 | 1 | 2 | 2 | 1 | 0 | 2 | 9 |
| 8 | 3 | 2 | 0 | 2 | 1 | 1 | 0 | 2 | 11 |
| 9 | 1 | 0 | 0 | 1 | 0 | 0 | 3 | 3 | 8 |
| 10 | 2 | 0 | 0 | 0 | 2 | 0 | 0 | 0 | 4 |
| 11 | 2 | 1 | 1 | 2 | 4 | 1 | 1 | 0 | 12 |
| 12 | 1 | 1 | 1 | 0 | 1 | 1 | 0 | 1 | 6 |
| 13 | 1 | 0 | 2 | 3 | 1 | 3 | 1 | 0 | 11 |
| 14 | 0 | 0 | 1 | 0 | 1 | 0 | 3 | 4 | 9 |
| 15 | 1 | 0 | 4 | 3 | 2 | 2 | 1 | 3 | 16 |
| 16 | 1 | 1 | 1 | 1 | 2 | 2 | 3 | 0 | 11 |
| 17 | 2 | 2 | 1 | 3 | 2 | 1 | 0 | 1 | 12 |
| 18 | 0 | 2 | 0 | 1 | 0 | 0 | 1 | 2 | 6 |
| 19 | 0 | 2 | 0 | 0 | 1 | 1 | 0 | 2 | 6 |
| 20 | 0 | 2 | 1 | 0 | 1 | 1 | 1 | 0 | 6 |
| Total | 23 | 20 | 19 | 24 | 28 | 20 | 27 | 26 | 187 |
The lower right cell shows a total of 187 catches.
In 20 fair games of 8 cards each with 15 numbers per card, the expected number of catches would be 20 × 8 × 15 × (20/80) = 600.
My results were 600-187 = 413 catches short of expectations.
The standard deviation of the total catches in 20 games is sqrt(20*8*15*(1/4)*(3/4)) = 10.606602.
This makes my results 413/10.606602 = 38.938013 standard deviations short of expectations.
In a fair game, the probability of 187 catches of less would be 1 in some number with about 330 digits. To put that in perspective, that would be like the chances of buying 39 random Powerball lottery tickets (each has a chance of winning of 1 in 292,201,338) and winning on all 39 of them.
You may be wondering if the game discloses that the ball draw is not fair. It does not that I can find. If you click the question mark in the game nothing happens.
It is easy to conclude either the cards or the ball draw is not random. I don't know exactly how they are doing it, but the numbers that appear least on the player cards are the most likely to be drawn.
Update
Hunter 3rd relic slot. After giving SmartSoft Gaming an opportunity to respond to this page, they replied that Slot Bingo was a work in progress and not available for actual casino use. Furthermore, they indicated it was not a good idea to have incomplete games on their web site, which I see they removed.
I would like to commend SmartSoft for doing the right thing and removing the game.

Fly Piggy Fly!What is the Bingo game?
We should thank the Italians not only for pasta, pizza, and wine but also for bingo. They invented this game in the 16th century, and people play it all over the world to this day.
Many of us learned about this game as a child, after visiting the local church with a devout aunt. Yes, don't be surprised. They often play bingo in churches. This game is not considered to be a hazard and has no restrictions.
In this game, everything depends on the chance of success. Each player gets a card with numbers in random order. The leader takes turns in the numbers, and the person checks the card for the numbers in it. The winner is the one whose card was the first containing the winning combination. Players who have numbers in a row, several rows, or a block receive a prize.
True bingo lovers can enjoy the game in special bingo online, free halls. But you can find interesting models in almost every online casino.
Free bingo variety and the basic rules
There're many models in this game. Let's check out the most popular ones.
The 90-ball bingo game is the most sought-after in Europe. The player receives a quad card with 3 rows of 9 cells. In each row, there are 5 cells, which are numbered, and 4 are empty. Thus, only 15 numbers from 1 to 90 are involved, which are chosen randomly. In the 1st column, there're numbers from 1 to 9, in the second – from 10 to 19, in the third from – 20 to 29 and so on.
The game begins with the launch of the lottery drum, from which balls with numbers are taken. You need to find these numbers and mark them on your card. The online version has a great advantage in the form of auto-fill function: the computer itself marks the necessary numbers. So you won't miss a single number.
The winner of the 1st game stage is the one who marks all 5 numbers in one line (row). The winner of the 2nd stage is the player who filled 2 lines. At the 3rd stage, you must cover the entire card. If at each stage of the game there are several winners, then the prize is given out equally between them.
The 75-ball Bingo game is most common in the USA. The card is divided into 25 cells – 5×5 squares. The card has the title 'BINGO', so each column has its letter. The 1st column under the letter 'B' includes numbers from 1 to 15, the 2nd column under the letter 'I' contains numbers from 16 to 30, and so on. The central cell is always free.
Just like in the above version, the balls are randomly drawn. The main task is to cover a certain pattern, which is proposed at the very beginning. There're a lot of different patterns. It can be ordinary letters, short words, and even various shapes. The winner is the one who first gets the winning combination. If several players at the same time mark the necessary figure, then they all get their winnings in equal parts.
The 80-ball bingo game is a new model of the beloved game, which is a lighter version of the 75-ball Bingo. The card is a 4×4 square. The columns are highlighted in different colors, as well as the corresponding balls with numbers. The rules of the game are very similar to the ones of the 75-ball Bingo. Here you also need to fill out a full card or collect some figure. The difference is that there is no free cell and there are fewer cells.
There is also a 30-ball model – an accelerated version of the game. The ticket has 9 numbers with 3 rows and 3 columns.
Why online Bingo?
Bingo has undergone many changes but this didn't affect anything other than the transition from ground-based bingo halls to an online game. Even if you're a fan of classic bingo games with printed cards, you should try to play free bingo online. There are several obvious reasons for this.
Firstly, you can play at any time of the day – online bingo games are available 24/7. If you have a very busy schedule, it's hard to find a few hours for your favorite entertainment. But online, you can relax even during your lunch break.
Bingo And Slot Games
You can play at any convenient place without being dependent on a casino and a bingo hall. Also, it makes no sense to spend time on a trip, if you're going to play no more than half an hour. Play Bingo online when you're stuck in a jam, or when you have to wait for something. Thus, the forced break will be really useful.
Secondly, emotional comfort is very important. Playing at your PC, you don't need to think about ethics rules and other people. The main thing is not to violate the rules of the game. You can start the drums and enjoy delicious food and drink, for which you don't have to pay large sums. Big advantage, right?
You can play using several cards at once. Moreover, the numbers are automatically marked on the cards. It's much more convenient than desperately follow the numbers for fear of missing at least one.
And most importantly, you can play free bingo games – no download, no registration is required.
Is it free?
Fans of gambling are used to paying for every spin. But yes, you can play free bingo games for fun and without any deposit – it's true!

Free bingo games are no different from playing for real money. You just enjoy your game without losing anything. Taking risk is good, but isn't a calm and relaxing game any better?
