Thunder Reckoning

By Mike Chen, Gaming Analyst

Thunder Reckoning is PG Soft’s collapsing Nordic slot that fills a five by six grid with symbols that activate, merge into larger blocks and finally turn into Prize symbols, and because Play Live has used it for a New Slot Drop free spins offer as well as carrying it as a regular lobby title, it is a game plenty of South African players meet early, so it is worth knowing how the activation ladder and the free spins fit together before you play for real money.

How Thunder Reckoning plays

PG Soft builds the game as a five column, six row collapsing slot with a base bet of 20, so winning symbols pay and then clear for new ones to drop in on the same paid spin, and every winning symbol also activates its position, which is the mechanic that feeds the Prize Symbols Feature later in the spin.

Thunder Reckoning RTP

PG Soft’s game information sheet gives a theoretical RTP of 96.76%, with 69.60% coming from the main game and 27.16% from the free spins, and our plain English guide to RTP explains why that figure is a long run average across millions of spins rather than anything you can expect from a single session.

Volatility

PG Soft rates the session volatility as medium and puts the overall hit rate at 28.01%, so some kind of win arrives on a little over one spin in four, while the free spins are much rarer at a hit rate of 0.56%.

Maximum win

The advertised maximum win is 5,000 times the bet of the winning spin, and PG Soft’s own simulation of one billion spins also lists a highest exposure of 5,000x, which is the payout of a full five by six Prize symbol at the top of its range.

Features and the free spins round

• Every winning symbol activates its position. The first time a position pays it is only partly activated, and the second time it becomes fully activated.

• Fully activated positions that sit next to each other merge into larger blocks of 2×2, 3×3, 4×4, 5×5 or, when the whole grid is fully activated, a single 5×6 block.

• When a spin has no more wins left and at least one fully activated position remains, the Prize Symbols Feature turns those blocks into Prize symbols that pay from 0.25x up to 5,000x of the bet depending on their size.

• Three scatters anywhere trigger 10 free spins, and each extra scatter adds 2 more spins. The free spins start with every position partly activated, keep activated positions for the whole round, end with a Prize Symbols Feature, and can be retriggered.

Playing on mobile

PG Soft builds its games for phones first, and the sheet lists support for iOS, Android and HTML5 with a portrait screen ratio of 19.5:9, so Thunder Reckoning fills an upright phone screen in the browser without needing an app download.

Thunder Reckoning demo

PG Soft offers a free demo of Thunder Reckoning from its game sheet, and trying it first is a sensible way to see how often positions fully activate before you put real money behind the spins.
