Gaming Glossary: FPS, Ping, Gacha, Battle Pass and More
A plain glossary of the terms you will see in every mobile game: FPS, ping, gacha, battle pass, skin, F2P, pay to win, nerf, buff and player ID.
· By the Krosty Shop team

Whether you play or you buy top-ups for someone who does, these terms come up constantly. Here they are without the jargon.
Performance and connection
- FPS (frames per second): how many images the game draws per second. Higher is smoother. Confusingly, the same acronym also means "first-person shooter".
- Ping / latency: how long your signal takes to reach the server and come back. High ping is why you "teleport" and shots do not register.
- Lag: the general symptom of slowness, whether from connection or device.
- Server / region: where the machine running the match is. Farther away means higher ping.
Money and items
- Skin: a cosmetic item. Changes appearance, not abilities.
- Battle pass: seasonal rewards unlocked by playing, usually with a free track and a paid one.
- Gacha: a random reward — you pay for a pull without knowing the outcome. From Japanese capsule machines.
- In-game currency: diamonds, gems, CP, UC, Robux — each game has its own, and it is what you buy when topping up.
- Bundle: a package combining several items for one price.
How games are described
- F2P (free to play): free to install, monetized through optional purchases.
- Pay to win: paying grants real competitive advantage, not just looks.
- Grind / farming: repeating tasks to gather resources or level up.
- Meta: the strategies or characters that are strongest right now.
Updates and community
- Nerf: weakening something in an update. Buff: strengthening it.
- Lobby: the waiting room before a match starts.
- UID / player ID: your identifying number. It is what a top-up needs — never your password.
- Cross-play: playing across different platforms (mobile, console, PC).
The term that matters most when buying
The player ID. It is public and lets a top-up reach your account without anyone touching it. If someone asks for your password on a game that tops up by ID, something is wrong.
Competitive play
- Ranked / rank: the mode where wins and losses move you through tiers (Bronze, Silver, Gold, Diamond and so on). Ranks usually reset each season.
- MMR and SBMM (skill-based matchmaking): the hidden number the game uses to match you with players of similar skill. It explains why lobbies get harder as you improve.
- Smurf: an experienced player on a new, low-rank account. Considered unfair and banned in several games.
- Sweat / tryhard: a player who plays every match at full intensity. "Sweaty lobby" means everyone is doing that.
- Carry: to win a match mostly on your own while the team contributes little.
- Clutch: winning a round alone against several opponents.
- K/D: kills divided by deaths. The most quoted stat in shooters.
- Camper / rusher: a player who waits in one spot versus one who pushes aggressively.
- Bot lobby: a match filled with computer-controlled players or very new accounts.
- Main: the character or weapon you play most.
Aim, input and hardware
- Refresh rate (Hz): how many times per second the screen redraws. A 120 Hz phone can show 120 FPS; a 60 Hz one cannot, no matter the setting.
- Input lag: the delay between touching the screen or pressing a button and seeing the result.
- Hitbox: the invisible shape the game uses to decide whether a shot landed.
- TTK (time to kill): how long it takes to eliminate an enemy with a given weapon.
- Aim assist: help the game gives to controller or touch players to keep the crosshair on target.
- Gyro aiming: aiming by tilting the phone or controller.
- Packet loss: parts of your connection that never reach the server; feels like rubber-banding even with low ping.
- Trigger clips: physical buttons that clamp on the phone for shooting; tolerated in games that do not allow controllers.
More money and progression terms
- Pity: in gacha games, a guaranteed high-tier reward after a fixed number of pulls without one.
- Banner: a limited-time gacha pool featuring specific characters or weapons.
- Top-up / recharge: buying in-game currency. In many games it is done with your player ID; the rest is explained in how to find your player ID.
- Loot box / crate: a purchasable box with random contents; regulated in some countries.
- Season: a period of a few weeks or months with its own battle pass, ranks and events.
- Premium pass: the paid track of a battle pass (in Free Fire it is the Booyah Pass, which replaced the Elite Pass in 2023).
- Cosmetics: anything that changes looks only: skins, emotes, sprays, banners.
- Microtransaction: any small purchase inside a free game.
- Gifting: buying an item for another player from within the game; not every game allows it.
Accounts and safety
- 2FA: a second code besides the password. Available in Riot, Epic, Supercell ID, Roblox and Steam.
- Player tag: the ID format used by Supercell games, starting with #.
- Region lock: an account or currency that only works in the region where it was created; it decides which top-up you need.
- Cross-progression: the same account and progress on phone, console and PC.
- Ban / suspension: losing the account permanently or for a period, usually for cheating, unauthorized software or account trading.
- Chargeback: reversing a payment with the bank; games treat it as fraud and suspend the account until it is settled.
- Account sharing: letting someone else log in. Against the terms of Epic and most publishers.
- Phishing: fake pages or messages built to capture your login. The reason support never needs your code.
Genres and chat shorthand
- Battle royale: many players, one map that shrinks, last one standing (Free Fire, PUBG Mobile, Fortnite).
- MOBA: two teams of five push lanes to destroy a base (Mobile Legends, Wild Rift, Honor of Kings).
- RPG / gacha RPG: progression through characters and gear; in gacha RPGs you obtain characters by pulls (Genshin Impact).
- Sandbox: open games without a fixed goal (Minecraft, Roblox).
- Auto battler: you build a board and the fight plays itself (Teamfight Tactics).
- GG, AFK, noob, OP, ez: "good game", "away from keyboard", beginner, overpowered, "easy". OP is also used for items that need a nerf.
- Patch notes / hotfix: the list of changes in an update, and a small urgent fix between updates.

Frequently asked questions
What is FPS?
Frames per second — how many images the game draws each second. Higher means smoother motion. Note the same acronym also names the first-person shooter genre.
What is a gacha?
A random reward system: you pay for a pull without knowing what you get. The name comes from Japanese capsule toy machines.
What does pay to win mean?
A game where paying gives a real competitive advantage, not just cosmetics. It is the most common criticism of a monetization model.
What is the difference between nerf and buff?
A nerf weakens something in an update; a buff strengthens it. Developers use both to balance the game.
What does "pity" mean in a gacha game?
A safety net: after a set number of pulls without a top-tier reward, the next one is guaranteed. Pity counters usually carry over within the same type of banner, so players plan their top-ups around it.
What is SBMM and why do my matches feel harder?
Skill-based matchmaking pairs you with players of similar hidden rating. As your stats improve, so do your opponents. It is not a bug and it cannot be turned off in most games.
What does region lock mean when I buy a top-up?
Some accounts and currencies only accept top-ups from their own region. Before buying, check the region shown in your profile or the product page, because a top-up for the wrong region cannot be applied.
