Overview
GigaRise is a game engagement mechanic (GEM) from Yggdrasil in which the reel grows taller when a special symbol lands on it. The taller the reel, the more symbols it holds, which increases the number of ways. Yggdrasil first introduced this mechanic to its portfolio in April 2021 with Atlantean GigaRise.
Unlike Megaways, where the height changes randomly on every spin, GigaRise only makes a reel “grow” when a specific symbol lands.
Reel Height and Number of Ways
In Atlantean GigaRise, each time a trident symbol lands, that reel rises by one row, up to a max height of 8 rows, and the number of ways grows to as many as 32,768. The number of ways is the product of all the reel heights. For example, in a 5-reel game where every reel has the same height, it works out like this.
| All reel heights | Ways (5 reels) |
|---|---|
| 3 rows | 243 |
| 4 rows | 1,024 |
| 5 rows | 3,125 |
| 6 rows | 7,776 |
| 7 rows | 16,807 |
| 8 rows (max) | 32,768 |
In the actual game, each reel has a different height. For example, with heights of 3, 5, 4, 3 and 8 rows, you get 3×5×4×3×8 = 1,440 ways.
Differences by game
Atlantean GigaRise (2021)
If another trident lands on a reel that is already at max height, the “Ancient Device” opens and you pick a bronze, silver or gold key to enter a bonus room. The jackpot here is a shared jackpot that builds up together with Yggdrasil’s Jackpot Raiders. Landing 3 or more shell scatters starts the free spins.
Dragon Lore GigaRise (2022)
Dragon Lore GigaRise, made with Bulletproof Games, is a 100-payline game. A reel rises when a dragon egg lands on it, and the raised reel stays that way on the next spin too. When a reel goes beyond 9 rows, you get 2 Super Wild respins in which the entire reel locks as wild.
Chilli Super Stars (2025)
Chilli Super Stars from Boomerang Studios combines GigaRise with DuoMax and OnlyWins. It starts at 243 ways, and during free spins the reels grow up to 6 rows, reaching up to 7,776 ways.

When Yggdrasil announced its partnership with Reflex Gaming for offline machines in the UK, it named GigaRise as one of its signature GEMs, along with GigaBlox, MultiMax and DoubleMax. It also makes a reel bigger, but it works differently from GigaBlox, where the symbols themselves get larger.
