It鈥檚 basically a matter of problem-solving.

That鈥檚 how Laura Benner ’25, an engineering and computer science double major, described cracking the . Joining her on the Kryptos team were her sister Renae Benner and her roommate Mana Acosta ’25, both engineering majors at EMU. On April 14, the team of three took first place in a contest featuring 151 students from colleges and universities across 16 states and Australia.聽

Since 2011, Central Washington University (CWU) has hosted this annual online competition for undergraduate students. The contest consists of three challenges that present brief scenarios along with some ciphertext. Contestants work individually or in teams to discover the original English plaintext message.

Students are permitted to use any resources available online to solve the puzzles. But the puzzles require a great deal of effort and critical thinking, far more than ChatGPT, for instance, can do. 鈥淚t鈥檚 really funny,鈥� Laura Benner said. 鈥淚f you give the entire puzzle to ChatGPT, it will spit back some nonsense solution to you.鈥�

Acosta and the two Benner sisters have all participated in the Kryptos challenge before and won first or second place. 

• 2025: First Place Team: Mana Acosta, Laura Benner, Renae Benner
• 2024: Second Place Team: Iris Anderson, Laura Benner, Renae Benner
• 2023: First Place Team: Mana Acosta, Laura Benner, Caleb Hostetler
• 2022: First Place Team: Mana Acosta, Caleb Hostetler, Hannah Leaman

Typically, an EMU team gets together on Thursday night when the competition opens and works until they solve all three challenges. This year, though, the team was able to solve only one challenge on Thursday night. Since CWU does not provide updates on students鈥� progress, they assumed they had lost. But on Monday morning, the last day of the competition, the team received an email saying nobody had solved the three challenges yet. They were shocked and immediately got back together to work on the puzzles again.

鈥淭he fresh start was good,鈥� Acosta said. 鈥淲e should have gotten together on Friday, but we were so sure that other teams had already won.鈥� The three worked quickly and managed to find leads that let them solve the last two puzzles. About 20 minutes after they submitted their Google form describing how they had solved the last puzzle, CWU sent a confirmation email that the EMU team had won first place.

EMU teams have historically performed well in this competition, and by now, they feel some pressure to win. While the 2025 team doesn鈥檛 know how other teams work, contestants at EMU usually dedicate a large block of time to working together. The room is typically silent, with individuals working on their own until someone finds a lead or breakthrough. Then they all talk it over and work together. The most challenging part of the competition is not losing motivation.

The first year Laura Benner joined the team, she didn鈥檛 know much about breaking ciphers and let other members take the lead. But this year she took more agency in solving the puzzles, and for at least two of them, she had 鈥渢hat electric moment鈥� of discovering the plaintext.

While her classes haven鈥檛 directly applied to learning ciphers, she said, 鈥淏oth engineering and cryptanalysis are highly logical. You need to be able to identify patterns and know when the route you鈥檙e going down isn鈥檛 working.鈥�
