The Four Inventions

The Four Inventions, developed by EURASIAN Gaming, features a video slot format with a layout of 5 reels and 3 rows, offering 25 fixed paylines. The game draws inspiration from the Four Great Inventions of ancient China: the compass, gunpowder, paper, and printing, with each invention depicted as high-paying symbols in beautifully crafted artwork. A wild symbol, represented by the Yin Yang, can substitute for all regular symbols except the scatter, aiding in the formation of winning combinations. When three or more scatter symbols land anywhere on the reels, players activate the free spins feature. During this bonus round, the game divides into four distinct reel sets, each corresponding to one of the inventions, with each set beginning with a designated number of spins; winning on a set can lead to additional spins for that particular set. Additionally, players have the option to utilize a bonus buy feature, allowing them to directly access the bonus rounds without waiting for natural triggers. The maximum win per line is limited to 32 times the line bet, with the higher-paying invention symbols yielding the most significant returns. After securing a win, players can choose to engage in a gamble feature, where they risk their payout for a chance to double it. Built using HTML5 technology, the game is accessible on both desktop and mobile platforms.
