Gaming Tools

Free online gaming tools for the math and lookups around your games — dice, mouse sensitivity, drop rates, names, and IDs — all running in your browser with no sign-up and no download. Top10k has 35 gaming tools covering tabletop, FPS, gacha, and chess.

For tabletop and RPG night, the Dice Roller rolls any combination of dice from d4 to d100 and shows the total. FPS players use the Sensitivity Converter to keep the same aim feel between games like Valorant, CS2, and Apex, while the DPI Calculator works out your effective DPI (eDPI) from mouse DPI and in-game sensitivity.

For gacha games, the Gacha Pull Calculator estimates the chance of landing a rate-up unit within a set number of pulls. The Steam ID Converter turns a SteamID into SteamID3 and SteamID64 for lookups and config files.
