What a PvP Duel Game Is, and Is Not
How a two-player duel differs from a crash game, a slot, and the other products sharing the name.
The defining property is your counterparty
In a crash game you play against a curve. A multiplier climbs, you decide when to cash out, and the curve breaks at a point the operator generated. Everyone in the round faces the same curve and the operator is on the other side of every bet.
In a duel you play against one other person. The stake is matched, the pot is formed from both stakes, and one of you takes it. The operator is not your counterparty. It takes a fee from the pot and has no position on which of you wins.
That single difference propagates through everything else: how the cost is charged, whether skill can matter, and what a fairness proof needs to establish.
Where the money goes
A machine keeps a proportion of everything staked, and that proportion is the house edge. It is charged whether you win or lose, on every unit that passes through.
A duel charges a rake on the settled pot. At a 10.00 USDT tier the pot is 20.00, the rake is 1.00, and the winner takes 19.00 — set out in what playing actually costs. If the round is cancelled, no pot settles and no rake is taken.
The practical consequence is that in a duel your losses go mostly to another player, not to the operator. That does not make them smaller. It does mean the operator's incentive is volume rather than your defeat, which is a meaningfully different relationship.
Whether skill matters
In a crash game, once the curve is generated the only decision is when to cash out, and the expected value of that decision is fixed by the house edge. There is no opponent to be better than.
In a duel there is. The blast point is pure chance and cannot be predicted, but when you pass is a decision, and passing sooner reduces how long the charge sits with you. Two players making different decisions do not have equal outcomes.
Skill is real here and it is bounded. It moves your win rate within a round; how much, and against whom, is the useful question. It does not move the rake, which is charged on every settled pot regardless of how well either of you played. Being better than your opponent is worth something; being better than the fee structure requires being better than your opponent by a specific margin.
What a duel needs to prove
A crash game has to prove one thing: that the operator did not choose the break point after seeing the bets.
A duel has to prove that, and also that neither player influenced the outcome. That is why both players contribute randomness and both contributions are required — if either is missing, the round is cancelled rather than resolved. An outcome derived from one party's input alone would be an outcome that party could steer.
It is a stricter requirement, and it is why the duel construction binds the match identifier, the round identifier, both client seeds and two counters into a single value before anything is derived from it.
Not the other Blinkos
Several unrelated products share this name. There is a note-taking application, an app-store title, and a family of Plinko ball-drop games, which are a different mechanic entirely — a ball falls through pegs into a payout slot, against a machine.
This Blinko is the 1v1 duel operated at playblinko.co. Two players, one charge, a hidden blast point, and a rake on the pot. If you arrived looking for a ball-drop game or a notes app, you are in the wrong place, and no amount of reading here will help.
