Overview
Large symbols (Colossal Symbols) are big symbols that take up several regular symbol positions as one block. Most are perfect squares with equal width and height, like 2×2, 3×3, or 4×4, and depending on the provider or game they are also called colossal symbols, giant symbols, or mega symbols. Because one big symbol covers several reels and rows at once, multiple paylines or ways can connect at the same time.
For symbol types in general, see slot symbol types. Yggdrasil’s trademarked version is covered separately under Gigablox. This article focuses on how large symbols appear and how wins are calculated.
How large symbols appear
| Method | Details | Example game |
|---|---|---|
| Merged reels | Several middle reels merge into one, and only a single big symbol spins. | Wolf Gold free spins (reels 2-4 merge) |
| Random drops | Large symbols of different sizes drop randomly on each spin. | Colossal Cash Zone (1×1, 2×2, 3×3) |
| Growing in stages | The large symbol grows one step bigger with each win. | Aztec Blaze (2×2 up to 4×4) |
| Guaranteed respins | After a win, every respin is guaranteed to bring a large symbol of a set size. | Colossal Gems (2×2, 3×3, 4×4 in order) |
| Bonus only | Only regular symbols appear in the base game, and large symbols drop only during free spins. | Money Mouse |
How wins are calculated
A large symbol counts as the same symbol sitting in every position it covers. So if a 3×3 large symbol lands in the middle of reels 2-4, it’s the same as having that symbol in all three rows of those three reels. If the same symbol also lands on reel 1 and reel 5, several paylines passing through that symbol can win at the same time.
In games like Wolf Gold, where reels 2-4 merge completely, the three middle reels always show the same symbol, so during free spins you only need that symbol on reel 1 to win easily. On the other hand, if the large symbol doesn’t match, all 9 positions on screen miss at once, so results can swing widely.
In Aztec Blaze, after the large symbol grows to 4×4, further wins add a multiplier that climbs up to 10x. Free spins start with 5 lives, and you lose one on each spin without a win that includes a large symbol.
How is it different from Gigablox?
Both have big symbols that take up several positions. The difference is in the name and the implementation. Gigablox is a trademarked mechanic managed by Yggdrasil, with set rules: on a ways layout, the big block is split and counted by the number of positions it covers. Large symbol is a general term that many providers use in their own way, so the trigger conditions, size, and whether the game uses paylines or ways differ from game to game.
