**Tour de Primes 2018**

Welcome to the 10th annual Tour de Primes. 2 is the first prime number...and the only even one. This makes it unique among prime numbers. Therefore, February is declared Prime month...being the 2nd month of the year. And there's no better way to pay homage to a prime number than to go out and find one. More precisely, a

**prime.**

__Top 5000__For the month of February, an informal competition is offered. There are no challenge points to be gained... just a simple rare jersey at the end of the month to add to your badge list. No pressure or stress other than what you put on yourself.

For 2018, we're adding four new badges you can win -- and these are available to everyone!

Results will be available at http://www.primegrid.com/challenge/tdp_2018.php.

As with the last few years, for all primes (BOINC and PRPNet) we're using the new reporting system whereby the prime's date of discovery determines whether it's eligible for the Tour de Primes. Prior to 2014, the date of

*verification*for BOINC primes was used while the discovery date was used for PRPNet primes. The current system is more intuitive and fairer.

**Note that SGS-LLR and GFN-15 are too small to be reported to the**

**primes list and are therefore**__Top 5000____not eligible for the 2018 Tour de Primes__.Currently, the fastest opportunities to find

**primes is with the PPSE (LLR), and GFN-16 (65536) projects. Of course, should someone find a prime in the mega-prime searches, this would certainly give them a good shot at the green jersey. Not a guarantee, however, as in 2017 there were several mega primes found in the Tour de Primes. Overall, in 2017 we averaged more than one mega prime per week for the entire year, so you might need more than "merely" a mega prime to take home green. In 2017 there were 10 mega primes found during Tour de Primes.**

__Top 5000__At the current time, PRPNet is not running. If that changes, all ports in PRPNet would be available for the competition.

To participate in BOINC PPSE (LLR), GFN-16, or any other eligible LLR or Genefer project, all you have to do is select it in your

**PrimeGrid preferences**. AP27 sequences are not reportable at T5K, so are not eligible for Tour de Primes.

Good Luck, have fun, and enjoy!
