Based on recent statistics for Diamond Explosion 7s, the simulated RTP stands at 88.74%, while the declared RTP is notably higher at 96.8%, suggesting a discrepancy between theoretical payout and actual simulation results. The hit frequency sits at 19.65%, indicating nearly one in five spins results in a win, with the average win emerging at 4.52 times the stake.

Theme

7 

The central theme of the Diamond Explosion 7s combines 2 retro-looking and popular themes - gems and fruits, which creates an ultimate nostalgic experience with the vibe of old machines. The design in Diamond Explosion 7s is honestly fairly decent: you have a vivid indigo background, simple but nice-looking reels made of gold, and music playing in the background to keep you entertained! As for the symbols, these are also done well, and there are 13 of them in total.

Regular symbols in the Diamond Explosion 7s are divided into low and high-paying ones; low-value symbols are cherry, plum, grapes and lemon - these have the same value of 0.10x, 0.20x, and 1x for 3, 4 and 5 symbols. Then there is watermelon, cloverleaf, bell, Bar, and 3 Seven’s - these are the high symbol value with 7’s being the most valuable.

In addition to the regular symbols, you also have four unique ones: Wild, Scatter, Prize Symbol and Prize Wild. Wild will replace all other payday symbols except Prize ones and Scatter, and during the Free Game feature, it will replace all symbols except, again, Scatter. The Scatter will pay anywhere on reels, and give you 5x and 20x for 4 and 5 symbols.

The Prize symbols will help you trigger the Link it Up Explosion feature if you collect 6 or more of them. During the Free Spins feature, 6+ Bonus Symbols and/or Prize/Wild symbols will also activate the Link it Up Explosion.
