Anyone engaging in, experiences virtual reels, in a virtual club, has knowledge of familiar designations, as "avalanche", "cascade mechanics", "Rolling reels", and "Tumbling reels". All of them refer to a similar algorithm. A victory chain is replaced with fresh images, which offers the chance to gain an further win on one reel spin. Classic 53 slots guarantee the slot player a single opportunity to form a payline sequence in each rotation. The player sets the reels in motion the spin and hopes that corresponding icons appear on the active lines. Simulators with cascading (avalanche, tumbling, etc.) falling reels operate in a specific manner, allowing the slot user a opportunity for another bonus reward. This is the process:

• After the turn, a reward combination comes together.
• The icons in the victory chain are removed (in some cases shatter) and produce empty gaps.
• In those empty spaces, new pictograms appear or descend.
• The player is rewarded, if the newly fallen icons similarly shape a reward chain collectively or with the leftover tiles on the racks.

Such a mechanism cycles until no payline chains are created on the paylines. Despite the different names, all the mentioned mechanisms act in the same way. The pioneering game in this category was Gonzo's Quest, designed and created by NetEnt and introduced in 2010.

Underlying reasons for the popularity of cascade-based machines 7slot

Users are no longer required to monotonously set in motion the drums and expect, until a win appears on one of the active pay rows. They are fascinated by a continually moving game structure and entertaining games, featuring refined imagery with stunning animation sequences and leading to special features, increasing the potential rewards. Cascading wave reels undeniably align with these demands. Developing bonus chains and together with this new images engage the player and heighten the excitement level. Especially when any of the waves triggers a substantial paying result.

Chain reaction reels empower players to earn numerous payouts in one turn. When payline combinations occur back to back, the rewards can build up into a extremely valuable sum. Some gaming studios embed bonus payout enhancers, that can escalate the reward.

Effect on theoretical return and volatility levels

Waves as a rule don’t impact the theoretical return to the player of slot machines. It’s possible to load machines with a greater financial return rate (higher than 97%) or a fairly reduced one (under 94%). No link exists between the emerging figures and the value of the theoretical return.

At the same time, reels with waves amplify the probability of a large prize. The working principle of the 7slots simulator makes up for the base round. Therefore, slots with a wave mechanics usually include a higher variance. Due to the fact that the drums might rotate up to two times (or multiple times) for the same price. This implies that prize sequences will not appear very frequently. Their regularity in avalanche slots typically is limited to 25-30%.
