For a while I have been playing Domino Dreams, that is available on the App Store for iOS which is Apple’s operating system and I would imagine they will also be available on the Microsoft store for Windows OS, and also for Android OS, which is by Google.
We first need to know how do you play the game? What is the goal that we are trying to achieve?
For this demonstration we are going to be using the photo that has been posted below.

Please take a moment to look at the current game board, with the given pieces are there any pieces that can match the piece that is in blue? I decided to color code them, so it would be a little bit easier to reference each piece.
and I would imagine they would also be available for android, which is a Google operating system. It seems to me. I personally think that when you start off playing for the first time it seems like they give you a whole bunch of rewards, prizes, and it seems like you always win, but then it seems that when you advance to different chapters and levels, it becomes harder, which is great, but I personally think when it becomes almost impossible especially when they try to what I think is only give you enough pieces or credits to be able to start playing and then if you want to finish you can, of course purchase an additional credits at an additional charge which is where I have the problem, but luckily, I found out a solution to where you don’t have to pay a single penny in order to successfully complete a game or two.
With every game that is available on the App Store for iOS starting at level one or the first couple of challenges being able to successfully completing a level or challenge and the odds of winning is much greater unfortunately as you move through the different levels or challenges at least for the first few 10 it is fairly easy to successfully complete and the odds of winning is still pretty good.
It seems once you advanced through The different levels or challenges being able to successfully complete a level or challenge in one sitting, and the odds of winning aren’t as great to when you first started out. However, there is a magic key number in credits that you should maintain and you should be able to successfully complete the level or challenge.

So how to successfully complete a level or challenge?
Each hour you will receive a certain amount of credits that you will use 90% of the time in order to play a game and to get a wildcard piece or to undo a move it will also cost you as well. Every so often you will earn a reward which can be a free play in which to play the game. It will cost you absolutely nothing as in points.
So why is it important to maintain a certain amount of credits?
PERSONAL OPINION: this may be how I am playing the game by not choosing the appropriate pieces. However, I personally feel that once you get below a certain threshold, you have one piece that is left over that won’t match anything and unfortunately you have to terminate the game which you lose everything therefore, if you have over certain amount you can afford to get two or three wildcard pieces in order to successfully complete the level or challenge .
if you run out of play credits, you always have the option to purchase an additional play credits. However, every hour you receive 3000 play credits, which is enough to play one game if you successfully complete the game, you earn credits in addition to other credits toward a bigger prize.
