Double Bubble Demo Slot
Double bubble is the second project I worked on at Gamesys. The game is a simple slot game for mobile with the additional mechanic of a bubble line and bubble pop bonus. Rebuilt from the ground up in javascript and HTML5 it is currently the highest earning game for the company.
My contribution to the project covered the following areas:
Audio – The sounds from the game were taken from the original flash version, compressed to a 64kb bit rate to suit mobile downloads and implemented for the spin, reel stops, win levels and bubble pop bonus.
The Double Bubble game is an exciting and rewarding slot game made by GameSys and just provided at the most excellent United Kingdom slot casinos. This game is based on a pretty idea, Double Bubble slot review features a winning sign like grapes, oranges, plums, melons, cherries moreover to Super 7, 1,2,3 bar and bell as well as the Double. Double Bubble is bubble incredibly popular multiline video slot game that double players of all pocket sizes a chance to spin and win high roller slots sums. As the name suggests, multiline slots have more than one payline, consequently giving you, as a player, a chance to wager across various lines on one spin.
Bubble Line – The bubble line is the meter present at the bottom of the game which reflects any bubbles currently shown on the reel-set, although the triggering of a win on this line is dealt with via https response from a server the icons on the line were implemented using Tween.js and Pixi.js.
Controls – The controls designed for the game are a standard across all Gamesys games and are injected into the DOM during the loading process, this injection was implemented via another team. My responsibility with this area was to ensure the game responded to the events sent from the controls such as mute, changing the bet lines, coin size and spin.
WinDisplay – The boxes and graphics that surround the icons of the reel-set during a win. My responsibility in this area was to draw the boxes and graphic (white background beneath the transparent icon of the reel). This was done using Pixi.js to draw the graphics in the right position. Additionally the smaller boxes that display the amount won per line were also part of this implementation.
Loading Screen – The loading screen of the game is a crucial feature, it is the entry point and the first thing the user sees when they start the game. Minus the logo and background (which is simply a canvas background set to the specific colour). The loading bar is the interesting part of this implementation.
The bar itself reflects the progress of several asset loaders running in the background via Pixi.js to load different aspects from the back end servers. These assets are determined via a bucket system and venture, the bucket system will define the boundaries of the screen and so will load the correct assets based on these reported boundaries, from the correct venture folder, in this case the venture is Virgin Games.
Additionally, the progress of the bar is forced to stop at 95%, this is to stop the user from believing the game has stalled when the bar reaches 100% and the game does not immediately start. The additional 5% reflects the game setting the assets up in the right place and waiting for the initial server handshake before showing the game, if this handshake does not get made for whatever reason an error is shown.
Bug Fixing – There were several bugs during the development process of the game. One bug that I’d like to highlight was related to memory usage within the game for iOS devices. The cache of an iPad can only support up to an OS Specific size, in our case the smallest size was 300MB. This meant that if any assets stored within the cache pushed the limit, the OS would automatically close the browser for using too much memory.
During development of the game we came across the browser crashing on an iPad 2 iOS 6. Not being sure of the cause I spent several hours tracking down the issue using instruments from Xcode to watch memory usage through the different parts of the game.
The solution to this issue lied within the drawing of the bet lines themselves. It was discovered that another developer had set the lines to cache as bitmap every time the line was shown rather than once. With 20 lines at a time and each one having the opportunity to be shown an infinite amount of times, eventually the cache limit would be hit and passed. Removing this setting to cache on draw proved an adequate solution to the issue.
Challenges:
Being the first game I have developed from start to finish using JavaScript, DoubleBubble presented many challenges, from learning another language having come from mostly a C, C++ and Java background to using several open source libraries such as Tween.js, Pixi.js, Howler.js and Node.js.
I learned not only the issues of developing for the mobile platform in terms of design, layout and problems involving rotation and screen size but also to better structure my code using the unique elements of javascript such as Closures and function callbacks.
Summary:
Since the game has been released I have moved onto other projects and my skill with JavaScript and game development in general has improved, I have learned from the mistakes made during development of the game and as a result the code written for the next games I am developing within Gamesys is shorter, more efficient and structured better to be more readable.

Today I thought I'm going to talk to you about the Double Bubble slots sites which you may or may not be familiar with. To fair, when players are looking for Double Bubble Realistic slot sites I really think they mean our beloved video slot game from Gamesys, however, there's another slot machine game with the same name, but oh boy, with a complete gaming experience.
The fruit machine I'm talking about was developed by a company called Realistic Games Ltd, perhaps you've hear of them because of their slot game ‘It Came From the Moon' slot, which I believe is much more popular than their Double Bubble game.

How to play Double Bubble online?
One of the first things I have to mention about this game is the looks. It's basically like playing at an old (very old!) fruit machine from a bricks-and-mortar casino or pub slot. It's a 5×3 reels layout with the choice to place wagers on up to 20 winlines.
BeGambleAware.org 18+ #adWinning combinations are built from left to right with a minimum of 3 matching symbols lined up on a payline; like pretty much any other slot game. There is also a Free Spins bonus game that can award 10 free spins, Scatter wins and a Bonus Game which is active during the Free Spins bonus game only. IMHO this Double Bubble slot does not provide a great gaming experience.
Unless we're talking about a classic slot machine that has been very popular with players in B&M casinos like 50 Lions slot from Aristocrat or Cleopatra slot from WagerWorks, I personally don't see why to make an online slot that looks like a replica of an old slot machine.

That being said, I find the graphics, animations and sounds to be quite dull. The winnings and the gaming experience follow this trend too. I played Double Bubble slot for a while, betting on all 20 paylines at 10 credits per spin and the winnings were seldom and very low in size.
For the most part, it was the Wild symbol that made it possible to build a winning line in this game. Most winnings were either 5 or 10 credits at the most with a very few winnings going as high as 70 or 100 credits.

The Free Spins bonus game which is activated by getting three or more Scatter symbols on the reels never came for me. I don't believe I eve got anywhere close to triggering the free spins, so I there is very little I can tell you about the potential for great wins during the bonus game.
The Double Bubble Bonus is another feature I cannot vouch for, as it is only available during the Free Spins game, you know, the one I never got to activate (snif, snif). It does spicy up the free spins bonus game which offers no multipliers for your winnings.
Getting the Double Bubble bonus symbol anywhere on the center reel will double your winnings up to the maximum jackpot prize of 10,000 x stake. If you fancy taking this alternative Double Bubble slots for a spin, there's a free to play version of Double Bubble at Ladbrokes or you can also play for real money wagers at Bet365.

I may just give this game another try sometime in the future, but it seems unlikely. Personally, I prefer the Double Bubble video slot game from Gamesys that we all know and love so much.
