Holly Molly Hole

An old miner and his trusty mole are the only guides players will need in Spinmatic’s Holly Molly Hole. The reels increasingly expand in this inventive, underground slot, with automatic re-spins increasing ways to win up to the maximum of 3,125.

Theme

Almost all of this slot’s game screen is below the earth’s surface, with only the miner’s feet (only one of which is shod) visible. Below the ground level, the mole watches the five reels spin, while a clock tracks the free re-spins progress towards their free spin finale. Gaming symbols include four kinds of valuable ores, with gold being the most profitable, as well as a collection of odd things to find underground: old boots, dinosaur skulls, wagon wheels, stone-age axes, ancient pottery, treasure chests, and oddest of all, part of the Statue of Liberty (perhaps this game is set on the Planet of the Apes). A pink worm symbol acts as wild. A banjo and harmonica-rich soundtrack adds to the down-home ambience.

Betting Options and Functions

Spinmatic tries an inventive approach in this slot, with a unique and very entertaining result. Instead of along traditional paylines, wins are paid whenever matching symbols appear in any position on three or more adjacent reels beginning with the leftmost. Bet level is set simply from 0.50–200.00 times the betting currency per spin. Autoplay is available for up to 100 spins, or without limit, with optional loss limits available on a separate screen. Player options, payline information, game rules, quick spin, and more are available via an expanding menu at the upper right corner of the game screen. The overall theoretical return to player ratio is slightly below-average, but still respectable at 94.47%.

Features

The unusual approach to slot gaming employed here will be obvious to players from the first, as not all reel positions are visible. There are ultimately five reels and five columns, but not all reel positions are active at first… rather, a free re-spin follows every base play win, with the reels gradually expanding on every re-spin. There are 135 ways to win in the first re-spin, 405 in the second, 675 in the third, 1125 in the fourth, and 1875 in the fifth.

After the fifth re-spin, the bonus feature is triggered. This takes the form of eight free spins with a whopping 3,125 ways to win. During free spins, the mole tosses dynamite up onto the reels with every spin, creating visual chaos at its most profitable.

Our Take

Spinmatic showcases some of its finest work in Holly Molly Hole. The ever-expanding reels create a completely one-of-a-kind gaming experience that will keep players coming back for more. If the RTP were just slightly higher, this title would be an all-time classic.
