In this article, I will introduce the basic concepts of Grids, which is one of the most popular slots among players

Not only do Grids make huge break through on traditional window shapes, but they also change the pay rule dramatically

Early Stage of Grids

The invention of the grid slot is recognized as having a strong connection with the inspiration of candy crash games. You can find some graphic designs that are similar to Candy Crash in grids, such as shapes of symbols and regular square windows

Before the first grid game was published, there were some prizes that could be triggered without the limitation of paylines, like the instant prize, but those prizes are more like features in slots. The main game still follows the traditional game rules and the limitation of paylines

Like the golden hawk symbols in upper picture can trigger instant prize without landing on a payline

Some people think Aloha! Cluster Pays is the very first grid slot. In this slot, there is a new game rule called cluster pays. Once there are no less than 9 same symbols appearing in a cluster, players can get corresponding payouts

Cluster pays can be triggered without the limitation of paylines, but it still requires the same symbols to land next to each other. Based on that, a more flexible game type was invented, which is Grids

As long as the number of symbols on the reels meets the requirements, players can receive rewards regardless of where the symbols are

In order to differentiate those two games, we can call the cluster pay one the iClusters, and the more flexible on Grids. However, there is no strict difference between them. You still can find some Clusters when you search Grids

Brief Introduction

As introduced in the upper content, grid slots just have requirements on the number of the same symbols landing on the reels, despite the exact landing area

Also, grid games normally have a cascading feature, which means when symbols match the winning requirements, they will cascade and there would be some new symbols added to fill the blanks

Normally, slots would use the upper way to fill the blanks

These changes make slot games much easier to understand. Owing to most symbols having different colors, players can easily find which symbols are more likely to win, during the spins and refilling of cascading symbols

Also, some grids add multiplier symbols in their game design. The random multiplier value works on all payouts players get in this spin. In some slots, the value can be added during the free games, which increases the variance of grids rapidly

Till today, those grids with cascading and multiplier features can be found in many regions' slot ranks. It is quite worthwhile designing one grid for your project. Just do not remember adding a bonus buy feature to shorten the time for reaching the excitement
