Online Ghost Slider is a slot machine game developed by Merkur, with five reels set in three rows. Its theme is inspired by ghosts, skeletons, tombstones, and other spooky elements which are not so realistically represented. This slot is similar to Eye of Horus.

There are 10 fixed bet lines, 10 regular symbols, and two Wild Ghost icons to make the gameplay entertaining and beneficial for players. The expected theoretical Return to Player (RTP) is 95.91%.

How to Win at Ghost Slider Slot?

When there are at least 3 matching symbols on adjacent reels, starting from the leftmost, you will lay a win. The icons will disappear, and new ones will come from above, while the skeleton will move the gravestone on the center of the screen.

When there are no renewed winning combinations, a juxtapositioned combo will end. After the 4th gravestone has been moved to the center, the number on it represent the number of extra spins you will get. Players are advised to play at the maximum bet to maximize their gains.

Options to Use

Auto Start – This is an auto mode developed by Merkur. On the bottom left corner, you can choose the number of additional spins: 5, 10, 15, 20, 30, 40, 50, 75, 100. Auto Start can be stopped on the same button. It will automatically stop after a big payment or if Spin Feature is activated.

GDC 2019

SAN FRANCISCO—This year's Game Developers Conference saw two game makers emerge with a possible chapter in a future dystopian sci-fi novel: the story of making money by letting robots do the work. In their case, that work was the procedural generation of smartphone games.

A single 'game jam' event led to a data machine that ultimately pumped out a decent amount of cash: $50,000 over a couple of years. Years later, with that data (and money) in hand, the makers of this game-making machine, which focused entirely on 'garbage' free-to-play slot machines, used GDC as a wake-up call to an industry where the 'right' messages often revolve around listening to players, sidling up to publishers, and racking up critical acclaim. In their case, eschewing all of that worked a little too well for their comfort level.

Winning the “race to the bottom”

In 2013, two video game makers had been trying for years to make it in the burgeoning mobile games space. One of them, Alex Schwartz, had helped get the solid mobile swiping-action game Jack Lumber off the ground. (In a past life, I gave that game a good review at the now defunct tablet-only magazine The Daily.) The other, Ziba Scott, had put together a fine mobile-friendly puzzle game, Girls Like Robots.

Both games operated in a pay-once, play-forever model without microtransactions. Both attracted awards, recognition, good expo showings, and publishers. Both failed to take off.

They looked at the meager income they were making doing it the 'right' way, as had been established by the old publishing guard. They then looked at iOS and Google Play marketplaces and saw that 'freewares, clones, and junk' dominate the general selection, let alone the actual money-making charts.

In one casual chat about the sheer weight of that business reality, the duo came to a conclusion: 'We could do better... at doing worse!'

They teamed up during the 2013 Global Game Jam to push something out that resembled the 'race to the bottom' they saw on mobile platforms. Thanks to the time-restricted nature of a game jam, they opted to buy a 3D slot machine asset off of the Unity Store (a marketplace that lets game makers pay modelers and animators for unrestricted use of various 2D and 3D assets) for $15. They then spent the rest of the jam creating a system that would automatically generate the rest of the skinning needed to make this basic virtual slot machine just unique enough to be published as its own smartphone app.

'Let's customize these like other slot machine companies do,' Schwartz said. 'They make themed slots. What's the minimum set of things to change to make a different slot machine? Let's change the title. Change the one image on the reel that might be relevant to your topic. So, like, a dolphin slot: put a dolphin in there [as the jackpot slot logo] with a special icon. Then the background is a scrolling dolphin image.'

The original word list was hand-curated based on what the team thought was interesting but also generic and safe-for-work. The most scintillating name they went for at that point was '3D Sexy Librarian Slots.'

With the visuals knocked out, the duo went one step further: creating custom music.

'A crappy song would play, then use text-to-speech to sing the word 'dolphin' in the Google Translate monotone voice. It'd play that every time you won. It'd say the name of your game in the music,' Schwartz said.

As a result, with the press of a single button, a Unity script could put those steps together and essentially auto-generate hundreds of 'custom' slot machines. Schwartz and Scott confirmed that their automated system's scraping of public images exposed one issue: Google Image Search would throw up errors for exceeding the rate limit. 'We found a use for Bing,' Schwartz said in a phone interview with Ars. 'Its image search had a number of things that were looser. I'm not trying to knock them, but they have a reputation for being second class. That felt like a kindred spirit for what we were trying to achieve here.'

“A portal to a better world”

With that slot-creation template set, the team automated the process of feeding information to Google Play (a much easier marketplace to exploit than iOS at the time) and creating publicly available freeware slot machine apps with ads. One simple Selenium script later, and that process was done.

The duo could feed a single slot-machine keyword into their combined scripts, which took 'a few hours' in all to build, then watch on a 'ghost monitor' as its system faked like a human, clicked every appropriate checkbox, picked every country, agreed to every terms-of-service agreement, and filled in every appropriate text box—then took the auto-generated slot machine and uploaded it for anyone to play.

Slot Machine Ghost Icon Set Download

They attached mobile ad network Playhaven to the whole thing because the duo's philosophy was that they never wanted to take actual money from users who would download their bizarrely named apps. They then 'walked away' for two months. After that period of dealing with real-life work, they peeked at their income and advertising statement and were stunned: people were downloading their apps, and 27 percent of those people were clicking on their ads, driving roughly $211 of ad revenue per day.

The team came up with a theory: 'All of our advertising keywords were related to casino related content,' Schwartz said to Ars. 'We had an epiphany: our game looks so fucking terrible, but people downloaded it for some reason. When they see an ad for a much better slot machine or casino, they click it because... of course you do! That's a greener pasture! A way better future you could be having! We think the quality was so low in our shit that the ads were a portal to a better world.'

Yet the duo incredulously admits that its average rating for many of the apps was in the four-star range and that reviews were quite kind. One review stood out to Scott, for the auto-generated '3D Bowling Slots' app: 'Someone wrote that they were disappointed that the slots didn't have much to do with bowling.'

Supervillain origin story?

The engineering half of their brains wanted to see how far this enterprise could take them. So they began tinkering with the existing template with things like the automation of slot-machine descriptions.

Google Trends seemed like a good idea, but that usually led to trademarked or public-figure names, and the team wasn't interested in getting out of the 'automation' loop by having to deal with a high volume of takedown requests. So they opted for a slightly updated app-name template: the word '3D,' plus an adjective, plus either an animal, location, or country, plus the word 'free.'

Examples included 3D Tremendous Face Pain Slots, 3D Rough Elbow Slots, 3D Mild Dogwood Slots, 3D Viceroy Butterfly Slots, and 3D Inexperienced Great Horned Owl Slots. (They eventually made T-shirts to commemorate the latter.)

Schwartz and Scott also paid a small Romanian studio a pittance to build a higher fidelity slot machine, which they eventually discarded. That happened in part because the duo's mix of newer full-time work and ethical concerns crowded out their excitement and availability.

'Someone said, you could raise money on this idea, or sell this data to someone else, or sell your company,' Scott said to Ars. 'We were at a crossroads where the joke was similar to the origin story of a supervillain. Do we abandon all creative pursuits to make the most intense money-making slot-creating enterprise? Or does this continue being a tiny background of 1/20 of our day?'

Eventually, the headaches of keeping up with Google Play caught up to the team. Apps were removed for violating an updated terms of service that gave Google more leeway to cut out apparent crapware. Google also updated the Web interface on a somewhat regular basis. Moving a single box a few pixels could throw a wrench into the Selenium robo-clicking works, which the team had previously designed to auto-upload 15 apps a day (Google Play's upload limit for a single developer account at the time).

At one point, the app network Playhaven called the duo with a flat declaration. 'We're seeing erratic data on your account,' Schwartz said to paraphrase. 'We're not sure what's up. We're not interested in continuing to serve ads to your slot machines. But we want to be clear: you didn't break our ToS. You're just, I don't know, inconvenient.'

Playhaven then added, 'You have the worst users. People who come from your apps don't spend money.' The team switched to another ad provider immediately, Chartboost. 'They knew roughly what we were doing,' Schwartz said. 'They've been great.'

“Optimized to remove our content”

This many years later, all of the roughly 1,500 apps generated by this experiment are dead. And Schwartz and Scott think of the whole affair as a mix of a joke and a productive wake-up call.

'Our half-joking argument: by offering the largest target of low-quality garbage apps, these marketplaces became optimized to remove our content,' Schwartz said to Ars. 'You could almost say that our company trained their algorithm so that what we were doing could eventually not be possible. But we were the first to bring it to that level.'

In their GDC presentation, Schwartz mostly left the data up for people to peruse in a laughing manner, but also with a human angle about the costs that might arise if you chase such a robo-generated app dream with profit, not laughs, as the goal.

'This whole project was an itch that felt so good to scratch,' Schwartz said at GDC. 'We thumbed our noses at the mobile market that had broken our hearts in 2013. We laughed the whole way... The truth is I don’t give a fuck about slot machines. We’ve moved on. If there’s a business lesson in that, I’d say: scratch your crazy itches, give that insane idea a try. But even if it does work out... be prepared to walk away because it may only have been the attempt that made you happy, not the result.'
