Neverknow is a virtual prediction game. You answer yes or no, build coupons, and play for NK points. NK is not cash. Nothing here is gambling.
A new account starts with 300 NK. You spend it as a stake and win it back when a coupon lands. You cannot deposit, withdraw, or buy NK.
A claim is a yes/no question with a closing time. Open claims show Yes and No odds. Pick a side to add that leg to your coupon. Odds on a placed coupon stay locked.
Standard odds stay put until the claim closes. Decaying odds drift toward 1.01 as the close gets nearer. Coupons already placed keep the odds they locked.
A coupon needs 3–15 legs. One leg is not enough. The odds multiply, and every leg has to be right. Stake between 10 and 50,000 NK. You can place 3 coupons a day and keep 15 open.
You can publish a coupon as a tip. Other players can like it or copy the open legs at the live odds. The weekly pack in the sidebar drops a ready set of legs onto your slip. You still place it yourself.
If a claim cannot be settled fairly, that leg becomes 1.00 and the coupon continues. If every remaining leg is void, the stake comes back.
Signed-in players can suggest a claim. If it is approved and opened, you receive 2,000 NK.
