How Kadena Nexus Games works
What do I need?
Linx or the Ecko app on your phone, or the Ecko extension on a computer, with a single-key k: account. Each wallet can win each game once a day.
How is a win checked?
Your puzzle is made on our server and the answer never reaches your browser. The server checks your finished puzzle and times it. Then the AI agent reviews how it was played before paying.
When am I paid?
Your prize is reserved in escrow for you as soon as you win. The AI agent usually pays within a few minutes, once Chainweb confirms the reservation. Every payment links to its transaction and an AI receipt.
What are the limits?
One win per wallet per round, one win per game per day, and a few attempts per round. Each try gives you a fresh puzzle.
What if the AI is unsure?
It never says no on its own. Anything unusual, like a solve faster than a person could manage, waits for a human reviewer.
Does it cost anything?
No. Playing is free and signing in sends no transaction. Prizes come from funded escrow, not from other players.
