Create a duel
Generates a code for seven prompts drawn from the 60-prompt bank. Send the link to your opponent; the same set opens on their device.
Open a duel
Received a code? Paste it here and the game will deal the same seven prompts.
That code does not look right. A duel code starts with d1 and is 16 characters long.
What is a Krillion 1v1?
A 1v1 is the same game as a solo dive with one change: the seven prompts are fixed by a code instead of shuffled fresh. That single constraint turns a single-player score into a comparison. If two people play the same seven prompts, the difference in depth is a difference in how each of them answered — not a difference in luck.
The duel is asynchronous on purpose. Live rooms are fun until one person is late, the connection drops, or a phone locks mid-prompt. A code has none of those failure modes. Send it at breakfast; your friend can play at midnight.
How a duel works
- Generate the code. The button above picks seven prompts and writes a link that contains them. Nothing is stored on a server.
- Send the link. Any messaging app works. Your friend opens it, taps Begin descent, and gets the identical prompts in the identical order.
- Compare the result. Each player finishes with a depth and a list of accepted answers. Higher depth wins; the share button copies a short result line if you want to post it in the chat.
Duel rules
| Players | 2, playing at their own pace |
|---|---|
| Prompts | 7, identical for both players and fixed by the code |
| Clock | 25 seconds per prompt in Classic mode; no clock in Zen |
| Scoring | Same six tiers: 10 / 15 / 30 / 60 / 85 / 100 points |
| Depth | Points × 10 = metres. Maximum 7,000 m |
| Winner | Higher total depth; tie-break is the deeper single answer |
| Cost | Free, no account, no expiration on the code |
Why the same prompts matter
In a shuffled solo game, a lucky set can carry you. One dive might hand you three categories you know cold; the next hands you three you do not. A fixed set removes that variable. The comparison becomes fair in the only way a trivia game can be fair: both players saw the same questions.
How to win a duel
The instinct is to play safe and take the correct answer. In a duel that is usually the losing move, because both players will get the safe answer. The edge comes from the second and third rungs:
- Bank the safe answer first in your head, then replace it. You lose nothing by spending three seconds considering the obvious answer and ten seconds looking past it.
- Take one calculated deep cut per dive. A rare answer you are confident about is worth six plankton answers. A wrong one is worth zero, so pick the prompt where your knowledge is genuinely broad.
- Do not skip the pack pages. Practice on geography, movies or sports builds the sideways recall a duel rewards.
Three ways to use a duel code
Challenge a friend
The obvious use. Send the link, play when you can, compare depths. Because the code never expires, the duel can survive a whole week of scheduling.
Run a classroom or office round
One code, any number of players, one shared set. Everyone plays on their own phone and reports their depth. It is a five-minute filler that needs no projector and no accounts.
Replay yourself
Play a set, read the results, then reopen the same code and try to beat your own depth. This is the fastest way to learn the bank: the prompts stay still while your answers improve.
Scoring refresher
Both players are scored by the same six tiers. The tier belongs to the answer, not to the player, so a deep answer is worth the same for everyone.
| Tier | Points | Depth | What it means |
|---|---|---|---|
| Plankton | 10 | 100 m | The answer everyone gave |
| Too Clever | 15 | 150 m | A sideways step, still crowded |
| Schooler | 30 | 300 m | A real move away from the crowd |
| Rare | 60 | 600 m | Genuinely uncommon |
| Deep Cut | 85 | 850 m | Very few divers found this one |
| Deepest | 100 | 1,000 m | The one in a krillion answer |
1v1: frequently asked questions
Does Krillion have multiplayer?
Yes, in the form of asynchronous 1v1 duels. One player generates a code, the other opens it, and both play the identical seven prompts on their own device. There is no live lobby and no real-time room, which means no waiting and no connection to drop.
Do both players really get the same prompts?
Yes. A duel code encodes seven specific prompt positions from the bank. When your friend opens the link, the game deals those exact prompts in that exact order, with the same 25-second clock and the same rarity tiers. Nothing about the set is random per player.
Who wins a duel?
The player with the higher total depth after all seven prompts. Depth is points × 10, so a 700-point dive is 7,000 metres. If the totals tie, the deeper single answer wins; if that ties too, the duel is a draw.
Can I play the same code more than once?
Yes. A code is not a ticket and it does not expire. Reopen the link to replay the same seven prompts, which makes it useful for practice: play once, note the answers the bank rejected, then try again.
Do I need an account to duel?
No. There is no sign-up and no friend list. The code is the entire invitation. Your scores are stored in your own browser, so each player sees their own result screen and compares depths manually or by sharing the result.
Is the 1v1 mode free?
Yes, like every other mode on the site. There is no charge for creating a code, opening one or replaying a set. The whole game is free, with no daily cap.
