- Triple Red Hot 777 Slot Review. What do the most traditional and vintage slot machines look like? In an age where slots have become bigger, louder and more layered with interactive gameplay during bonus rounds, it’s challenging to think of where the old-fashion slot machines fit.Have all the features of a three-reel slot completely been replaced by digital, five-reel, four-row behemoths?
- Along with alternative online slots from Gamomat designers, Take 5 Golden Nights Bonus is packed full of fun. With symbols like sevens, stars, bells, plums, oranges, lemons, cherries and diamond this fruit based online slot machine is a blast to play.
The free online Hot Seven slot machine is video game developed by Amatic Industries. It has 5 reels with 3 rows and 5 paying lines that cannot be adjusted. Hot Seven slot machine game has an old-school design, and everything about it is completely retro, like the fact that it has no bonus games, and even its sound effects remind of old gambling machines.
Hot Seven Slot's Burning Tokens
The Hot Seven slot game has a total of 9 symbols, out of which only one is a bonus symbol while all others are those of a regular kind. To see the amount each card gives, there is a question mark sign which when clicked opens the pay table. The symbols can be categorized into following categories:
- Low Win Icons – 4 regular-type icons, all depicted with fruit (cherry, lemon, orange and plum). One can win 200, 500, or 2000 credits depending on whether he collects 3, 4, or 5 of the same card. The cherry even awards 50 credits when one gets only 2 of them.
- High Win Icons – another 2 regulars, depicted with grapes and a watermelon. They award 500, 2000 or 5000 credits depending on whether 3, 4 or 5 of the same one is collected.
- Jackpot – marked with the number 7, and if one gets 5 of them, he is awarded the maximum win of 50000 coins! If 3 or 4 jackpots appear on the reels, the player is paid either 1000 or 10000 coins.
- The Scatter – depicted with a star, the Scatter represents the only bonus symbol. It is the only symbol which pays in any position, every other pays from left to right.
Gamble Option
When playing Hot Seven free slot, the player can choose to risk his winnings of the previous round in order to double or even quadruple that win. That is done by picking the Gamble mark, just by choosing the same-named button whenever something is won. When the gambler decides to use the Gamble option, he is about to choose a card's color or suite.
If he guesses the card's color, his winnings are increased, while if he picks the right suit of the card, the player's winnings of the previous round are quadrupled. If the gambler's guess is incorrect, everything he has gambled is lost. Also, if the player prefers to risk a lesser amount, he can click the half button in order to cut the gambling bet in half. This can be done until only 1 credit is reached.
Playing & Wagering
Hot Seven has the two, probably already known, ways of playing. Those are the manual, by pressing the Start button each time the gambler wants to spin the reels, and the automatic, by clicking the Auto Start button which spins the reels for unlimited number of times. The Auto Play lasts until the gambler has lost all of his credit or until it is stopped.
This gambling machine is rather flexible on the one hand, since it gives its player an option to set the bet per line from 2 up to 1000 coins, which makes the maximum total bet 5000 credits. On the other hand, it has only 5 paying lines which are also fixed. The information considering the standings (Balance, Total Bet) can be checked in the bottom of the screen, which is also where the Bet is adjusted by clicking the button carrying the same name.
Who Can Play Hot Seven Free Slot?
Not much is needed to use this retro online slot machine. No download is required; the gambler just needs a stable internet connection and either a mobile phone of a newer date or a PC to take pleasure in playing this old school gambling machine game.

Introduction
In my continued efforts to show the world how video slot machines work, I set out to deconstruct how Blazing Sevens was designed by playing it. There are lots of different 'Blazing Sevens' games. The one I am referring to is the five-reel video slot. Armed with a cell phone camera, I recorded about 30 minutes of play. Unlike most video slots, Blazing Sevens has no bonus round. To analyze the game, all I needed to do was piece together the reel strips based on my videos and then do the math.
Step One - Data Collection
Much like games I previously deconstructed, Jackpot Party and Hexbreaker, I chose Blazing Sevens because it didn't involve bonus spins. The only mystery was the reel stripping. So I found a game in the Fremont in downtown Las Vegas and recorded 30 minutes of play. These videos can be found on YouTube:
- Blazing Sevens part 1(10:07)
- Blazing Sevens part 2(9:12)
- Blazing Sevens part 3(10:04)
When I returned home, I asked for volunteers to record each sequence of three symbols on all five reels for every spin. I would like to thank Miplet for transcribing part 1 and ChesterDog for part 3. Those two videos I felt were sufficient.
Step Two - The Reel Strips
Then I tried to put together the order of the reel strips, based on the observed sequences of symbols. To make the reels balance and loop around, I assumed that some sequences appeared more than once on the same reel strip. These were chosen according to what completed the reels and which sequences occurred more frequently. The reel strips below I believe are very close approximations to the actual ones. However, due to repeating sequences, and a limited sample size of 617 spins, they are probably not exactly correct. I estimate that each reel may have about two incorrect symbols in terms of frequency.
The following table shows how often each three-symbol sequence appeared on each reel in videos 1 and 3. For example, the D-7-1 (dollar, plain seven, 1-bar) sequence appeared 14 times on reel 1.

My sidekick, JB, then wrote a program to assemble the combinations in order. It should be noted that given the sequences observed, multiple solutions are possible. The reel strips below are just one possibility. However, all of them would have the same expected return.

The way multi-line video slots work is they draw random numbers, one for each reel, to determine where on the reel strips to stop. In this case, the game would choose five random integers from 1 to 40, one for each reel. Suppose, for example, the game chose the numbers 24,24,37,11,4 for reels 1 to 5 respectively. Then assume the game maps these number to the top row seen on the screen. In this example, the screen would look like this:
The next table shows the total number of each symbol on each reel, based on the estimated reel strips above.
Blazing Sevens Symbol Distribution
Symbol | Code | Reel 1 | Reel 2 | Reel 3 | Reel 4 | Reel 5 |
---|---|---|---|---|---|---|
Blazing seven | F | 1 | 5 | 5 | 5 | 10 |
Seven | 7 | 7 | 5 | 5 | 5 | 5 |
Dollar | D | 6 | 9 | 9 | 7 | 5 |
Bell | B | 9 | 8 | 9 | 7 | 8 |
3-bar | 3 | 7 | 3 | 3 | 5 | 4 |
2-bar | 2 | 6 | 5 | 5 | 4 | 5 |
1-bar | 1 | 4 | 5 | 4 | 7 | 3 |
Total | 40 | 40 | 40 | 40 | 40 |
Step Three - The Pay Table
The pay table is easily seen from the rule screens and game glass. Most video slots simply multiply all awards by the number of coins bet per line. Blazing Sevens is different. The first coin enables wins on the dollar, bell, and all bar symbols. The second coin enables wins on all types of sevens. The third coin doubles the wins on plain sevens and mixed sevens, and more than doubles the wins on blazing sevens. The following three tables show the pay table for 1, 2, and 3 coins bet per line respectively. All wins must be left-aligned.

Step Four - The Math
The next table shows the number of combinations for each possible win. In cases where two equal wins are possible, for example three 3-bars or five mixed bars, the game counts it as the one composed of fewer symbols.Blazing Sevens Line Pay Combinations

Total | 685,922 | 1,731,003 | 5,657,600 | 8,074,525 |
The next table shows the probability of each possible win. The values in each cell are the number of combinations from the table above divided by the number of combinations of 405 = 102,400,000. The lower right cell shows the hit frequency per line of 7.01%.

If I didn't make myself clear above, I am not claiming this page is an exact depiction of Blazing Sevens. Due to repeating symbols, I had to make some judgment calls to fill in the blanks. As explained above, there are also different reel strip orders possible given what was observed at the machine.Acknowledgments
I would like to thank miplet for doing the data entry on video 1 and ChesterDog for video 3. I would also like to thank JB for piecing together the 40 different sequences of three symbols for each reel into a complete reel strip, as well as for confirming my math was correct.
