A design and formal verification holiday puzzle that involves, flowers, leaves, branches and even bees.


December 20th, 2018 – By: Sergio Marchese


The holiday season is all about traditions, and the annual holiday puzzle has become a tradition here at OneSpin. Two years ago, we challenged engineers everywhere to solve the famous Einstein’s Riddle using a formal tool. We received some interesting solutions. Last year, we drew an even bigger response to our invitation to tackle the “World’s Hardest Sudoku.” These puzzles are fun, of course, but the different approaches taken by those submitting solutions also reveal a lot about the power and flexibility of assertions and formal verification.
