Arcade video games are often composed of short levels, intuitive control mechanisms with a rising difficulty. This is the main concept of an arcade video game in which the player is essentially obliged to pay to maintain the play. An arcade game has, as its main feature, the impossibility for the player to win. 'The game ends invariably to overwhelm the player, by becoming unplayable, and overcome by saturating the capacity of the player. An arcade video game is based on the fundamental principle of the player's overflow by the game'. A console or computer game can be considered as an arcade game if this game shares same qualities (or if the game is a direct port of the original arcade title).

The video games, our childhood's passion...

A video game is an electronic game that involves human interaction with a user interface to generate visual feedback on a video device. The word video in video game traditionally referred to a raster display device, but it now implies any type of display device that can produce two- or three-dimensional images. The electronic systems used to play video games are known as platforms; examples of these are personal computers (computer softwares), consoles (console video games). These platforms range from large mainframe computers to small handheld devices.
In most recent times there has been huge growth in mobile gaming with more readily available portable devices such as smartphones and tablet computers.
The history of video games goes as far back as the early 1950s, when academics began designing simple games, simulations, and artificial intelligence programs as part of their computer science research. Video gaming would not reach mainstream popularity until the 1970s and 1980s, when arcade video games, gaming consoles and home computer games were introduced to the general public. Since then, video gaming has become a popular form of entertainment, a part of modern culture in most parts of the world.

Whenever 2, 3, 4 or 5 Scatters show up on the reels within the feature, you will win 5, 8, 12 or 20 extra free games during which Wilds will turn into multipliers to increase your payouts when included in winning combos too.

Overview

Secret of the Mermaid is another Konami-powered slot machine originally created for land-based casinos.

The symbols in bright colours land on the ultramarine blue reels, yet the game looks dated. The same goes for sounds which are generic and mechanical like those playing in land-based slots.

The biggest attraction of the game is its free spins feature with Wild Multipliers increasing your wins by up to 5x. Once you enter the feature, you will easily re-trigger it as it requires only 2 Scatters and enjoy numerous rounds without risking your own money. The mermaid symbol pays when only 2 of a kind land on a payline in succession starting from the leftmost position, but you will win only 2 coins for such a winning combination.

The truth is that regular symbols award mediocre prizes, so if you are looking for more rewarding gaming experience, keep an eye on Scatter to enter the free spins round with up to 5x multipliers.
