Week …
Call the next blocks.
Guess how Koinos block producers will do. New questions drop Monday to Saturday, and every right answer is a point. Stake VHP to play for real: each week, the top scorers split the blocks our pool earns. Or just play for free.
Today's questions
Answers close when the timer hits zero.
Waiting for the blocks
Answers are locked. Results appear when the window's blocks are final.
Leaderboard
Points count as soon as each question's blocks are final. The top 30% of staked players win, and ties at the line win too.

Results
Every answer comes straight from the blocks. Each result has a fingerprint (hash) of the blocks used, so anyone can check it.
How it works
A weekly game about the Koinos chain. Your stake keeps producing blocks for the pool the whole time.
Play free, or stake VHP
Anyone can answer and climb the leaderboard for free. To share in the rewards, stake at least 1 VHP (whole numbers only), or KOIN, which is burned into VHP. A stake counts from the next week. You can withdraw any amount at any time, down to the last decimal. Withdraw part during a week and you keep playing with the lower stake; withdraw everything and you're out for that week.
Answer daily questions
30 questions a week: 5 new ones every Monday to Saturday at 12:00 UTC, and answers close at 00:00 UTC, 12 hours later, before the blocks they ask about are produced. Every correct answer is one point. Sunday is results day.
The week closes
95% of the week's block rewards go to the winners (5% producer fee). The top 30% of staked players win, ties included. Higher places earn more: most of what the seed earns is shared by place alone, so a 1 VHP player can win big; the rest is shared by place × stake, so staking more pays more. Winners are final Tuesday 12:00 UTC. No winners? The pot carries into next week.
Collect your reward
Your reward is paid in VHP. After a 5% producer fee, the top 30% of staked players win, counted by headcount, and ties at the line win too. The pot is two baskets: one shared by finishing place (each place weighs 1/√rank, so first place weighs the most), and one shared by that place weight times your stake. Unclaimed rewards wait for you, and keep producing for the pool meanwhile.
Who decides the right answer?
The blocks do. After a question's window ends and the blocks are final, the answer is computed from them and published with a hash of the exact blocks used. If a producer in a question goes offline, the question is voided and doesn't count for anyone.
Does it cost anything to play?
No fees. Koinos uses Mana, which refills on its own. If your Mana is low, tick Kondor's free Mana option when you confirm. With KOIN Vault on your phone, holding a little KOIN gives you the Mana.
Can anyone take my stake?
No. The contract only sends your stake back to you. The owner can't move players' stakes or rewards, and code changes must be announced 48 hours ahead so anyone can withdraw first.
