- Is every emoji equally likely?
- Yes. With All selected, each of the 319 emoji has exactly a 1 in 319 chance, about 0.31%, on every pick. The randomness comes from your browser's crypto.getRandomValues, the same source password generators use, not Math.random. A 32-bit random number can't be split evenly into 319 parts: 103 of its 4,294,967,296 possible values are left over. Those values are thrown away and a new number is drawn, so no emoji gets even a tiny head start. That's called rejection sampling.
- Why don't I see every emoji that exists?
- Because a lot of them wouldn't show up on your screen. Unicode has over 3,600 emoji and adds more every year, but your operating system only draws the ones its emoji font knows. Anything newer renders as ▯, an empty box nicknamed tofu. For a picker that's a nuisance; for a random generator it's fatal, because the broken box IS the whole output. So this pool is capped at Unicode 13.1 and hand-checked: 319 emoji that render on Windows 10, macOS 12, Android 11, iOS 15 and everything newer. No flags, no skin-tone variants, no 2022-and-later additions.
- How does No repeats work?
- It draws from a bag. Each emoji comes out once and doesn't come back until the bag is empty, and the bag survives between clicks — pick one at a time from Animals and you'll see 38 different animals over 38 presses. The counter under the display reads how many are left in the category. When it hits zero the button changes to Start over, and pressing it refills the bag and picks right away. Ask for more than the bag holds and you get only what's left, never a padded batch with duplicates.
- Why do I keep getting the same emoji twice?
- Because repeats are normal when every pick is independent. Pull 20 emoji from a 319-emoji pool and there's a 45.6% chance at least two match. By 30 emoji it's 75.5%. That's the birthday problem, and it surprises people every time — the odds of a collision climb far faster than intuition says. If a repeat would ruin your game, turn on No repeats.
- What does Copy actually put on my clipboard?
- The emoji, joined with nothing between them: 🔥 for one, 🔥🎉🚀 for three. No spaces, no commas, no trailing newline. The gaps you see in the grid are layout, not characters. That matters because most places you'll paste — a chat message, a channel name, a spreadsheet cell — treat a space between emoji as real text.
- Can I use it from the keyboard?
- Yes. Press Space or Enter anywhere on the page to pick again, as long as you're not typing in a field. Space inside the How many box still types a space. Every press is a fresh pick with no animation to wait through, so you can run a whole round of an emoji guessing game without touching the mouse.
- What's a good way to use this in a game?
- Emoji Pictionary is the easy one: draw three emoji, and a player has to act out or describe a phrase using only those. For a harder round, set Category to Food & drink and How many to 5, then have the team invent a recipe. Teachers use single draws as a writing prompt — pull one emoji, write two sentences about it. Turn on No repeats so nobody gets handed the same prompt twice.
- Do the emoji look the same for everyone?
- The character is identical everywhere; the picture isn't. Apple, Google, Microsoft and Samsung each draw their own artwork for the same codepoint, so 😬 can look nervous on one phone and cheerful on another. That's out of anyone's hands — what this tool controls is whether a glyph exists at all on your system, which is why the pool stops at Unicode 13.1.
- How is this different from the emoji picker and emoji search?
- Intent. The Emoji Picker is for browsing when you'll know it when you see it, and Emoji Search is for when you know the word but not the emoji. Both assume you have a target in mind. This one assumes the opposite: you don't know and don't care which emoji you get, you just want one. That's why there's no search box here and no grid to scroll.
