It's still not too late to get onto http://www.pidaychallenge.com and work through 24 puzzles to get onto the Genius board. You may work at the puzzles at your own pace. Last year it took me 1 week (after work hours) to complete all the puzzles.
Even though I don't believe 2016's puzzles are as hard as last year's challenge, it was quite entertaining and, based upon the stats, still hard enough that only 10% (or less) successfully work all problems. There were logic, probability, algebra, geometry, and physics problems/puzzles/questions.
Enjoy the challenge!
