The KenKen International Championship (KKIC) will be 3 rounds, each with three puzzles per round. Each round gets progressively harder.
There are three Student divisions separated by age, an Adult Division, and a Senior (60+) Division. All will have awards and prizes for the top 3 finishers in each division.
The Adult and Senior Divisions will receive the same puzzle sets. Each Student Division will have its own unique puzzle set.
The winners of each Student Division will compete with each other to solve a 7x7 puzzle. The winner will be named the KenKen International Student Champion. The top 3 qualifiers of the combined Adult and Senior Divisions will compete in the Championship round for the title of International KenKen Champion. There will be cash prizes, trophies and KenKen swag... and of course bragging rights!
See the lists lower on this page for a breakdown on what puzzle types each division should be prepared to solve during the competition.
No solving aids such as calculators are permitted. Scrap paper will be available on each table.
At sign-in you will receive a KENcil (special KenKen pencil). You may use this or bring your own writing utensil.
All answers must be clear and legible. For example, be careful that notes aren't confused with the actual answer in any box! The judges decisions are final.
Scoring is based on a combination of accuracy and speed. The scores will be calculated as follows:
1000 points will be awarded for each successfully completed puzzle.
“Time bonus” points for speed will be calculated as follows:
Total possible “time bonus” points per round is equal to the time limit in minutes for the round multiplied by 30. For example, Round 1 is for 18 minutes, so the total possible “time bonus” points are 540. 5 “time bonus” points are deducted for every 10 seconds of solving time as the clock counts down to 00:00.
