Supercell's three biggest live titles share a premium currency called Gems across all of them, but what that currency actually buys — and how essential it is to progress — differs significantly by game.
Clash of Clans: base building and long-term strategic progression
Clash of Clans Gems primarily speed up building and troop-training timers, plus unlock cosmetic decorations for your base. Clash of Clans is built around a long-term progression loop measured in days and weeks rather than session-to-session — Gems are most valuable here for players who want to accelerate that long build-up rather than waiting out timers naturally, which the free-to-play game fully supports if you're patient.
Clash Royale: real-time card battles, Gems fund card unlocks and chests
Clash Royale Gems primarily buy chests (which contain cards and other currency) and speed up chest-unlock timers in this real-time 1v1 card battle game. Unlike Clash of Clans' long building cycles, Clash Royale's core loop is fast matches, so Gems here are more about accelerating your card collection than waiting out a construction timer.
Brawl Stars: fast 3v3 matches, Gems fund Brawl Pass and cosmetics
Brawl Stars Gems fund the Brawl Pass (the game's seasonal battle pass) and cosmetic skins for characters, in a game built around quick 3-minute matches rather than either of the other two titles' longer-term structures. Progression here leans more on skill and match frequency than currency spend compared to Clash of Clans' more currency-accelerated building loop.
None of these three require spending to be fully playable
All three are genuinely completable and competitive without spending — Supercell's games are consistently regarded as some of the more fair free-to-play titles in the mobile space, where Gems accelerate progress rather than gate core content behind a paywall. Spending here is about convenience and cosmetics more than a hard requirement to compete.
Seasonal content timing affects value
Like most live-service mobile games, timing a Gem purchase around a new season or event in any of the three typically gets more value than spending generically — check the current in-game season calendar before topping up if you want to maximize what a purchase actually unlocks.
You can't share currency between the three games
Despite sharing a developer and a currency name, Gems don't transfer between Clash of Clans, Clash Royale, and Brawl Stars — each game's Gem balance is entirely separate, so buy specifically for whichever title you're actually playing rather than assuming shared value across the trio.
Clan and social features differ across the three
All three support clan or team-based social features, but the emphasis differs — Clash of Clans' clan wars are a core long-term social structure, while Brawl Stars' club system is more casual, and Clash Royale sits in between with clan-based card donations supporting individual progression. Worth considering if playing with a consistent group of friends matters as much as the core gameplay loop.
Quick FAQ
Can Gems be transferred between Supercell games? No. Gems are tied to the individual game and cannot be shared between Clash of Clans, Clash Royale, and Brawl Stars.
What are Gems mainly used for in Clash of Clans? They primarily accelerate building and troop-training timers, with some additional cosmetic uses.
What do Gems buy in Brawl Stars? Gems are mainly used for seasonal Brawl Pass content and cosmetic skins.
The bottom line
Long-term base-building strategy: Clash of Clans. Fast real-time card battles: Clash Royale. Quick 3-minute team matches: Brawl Stars. All three, plus other mobile top-ups, are in Mobile Gaming Top-ups.
