The Nikoli Derby - 6th world championship

Entry to The Nikoli Derby was closed

We will announce the ranking of all participants on Tue. Sep 2nd.

The Nikoli Derby was developed by nikoli as a party game. It has very simple rules that make it exciting and easy for all, from kids to much older players. The number of players can be from 10 to 5,000,000,000 so The Nikoli Derby is enjoyable at any party. nikoli holds this derby with readers and customers at any chance we get.

Previous the Nikoli Derby that held only on the English pages, we received maximum 99 horses' entry. But for this World Championship, we accept Japanese horses from Japanese pages, so we expect more than 500 horses will be lined up at the start line.

Please register from the entry form at the bottom of this page.

What you need to do

You are the owner of a racehorse, and there are two things you need to do to take part in the derby.

  1. Enter the name of your horse.

    Please think of a good name for your horse, between 2 and 24 letters.

  2. Choose a starting gate number.

    Pick your favorite number, from 1 to 200, as your starting gate.

That's all. But note: you can only enter one horse! Please read the "Note" below.

How the winners are ranked

The gate number is the key to winning the Nikoli Derby. The smallest gate number chosen by only one person is the winner. If two or more persons choose the same gate number they will lose the race. This means that you have to choose the smallest number that nobody else has chosen to win the race. What is the smallest number from 1 to 200?

Right, of course gate number 1 has the greatest advantage, but other horse owners know that too. If say, two or more horses are entered for each of gates 1 to 50, then the horse starting from gate 51 will win. Now, you have to guess the "smaller number" of those where you will be the only starting horse. The final ranking is ordered from smaller to larger numbers.
