  • Unique and clever math puzzle game that challenges players to reverse engineer mysterious calculator operations.
  • Well-designed difficulty curve that starts accessible and becomes increasingly challenging, rewarding logical thinking and experimentation.
  • Engaging theme and aesthetic that adds character and humor, making math puzzles enjoyable for math enthusiasts.
  • Built-in calculator interface is clunky and unintuitive, lacking useful features such as backspace and key mapping for functions.
  • Occasional bugs and UI issues like window resizing problems and unclear menu navigation can hinder gameplay experience.
  • Limited educational value for formal learning as the game focuses more on puzzle solving than thorough mathematical concept teaching.

    6 mentions Positive Neutral Negative

    The gameplay is centered around a clever and thematically integrated puzzle mechanic where players use calculator functions to reach the number 666, with unique constraints that enhance challenge and strategy. However, the UI can feel slightly cumbersome, potentially hindering immediate engagement with the core gameplay. The developer also seeks to connect the mechanics with higher-level academic concepts, indicating a thoughtful design approach.

    • “Devil's Calculator is a puzzle game focused on the mechanic of creating the number '666' using all the functions on the calculator.”
    • “It helps that the developer found an insanely clever way to present the gameplay through its theming: the goal of every level is to use the operators to create the number 666.”
    • “The unique decimal representation works well with the mechanic to disable certain buttons (e.g., if the operator allows neutral operations with certain inputs, just disable the 6 button so players can't simply type 666 and perform a neutral operation).”
    • “The UI makes it slightly cumbersome to get to the meat of the gameplay.”
    • “The following line was in the email I was sent: 'We're reaching out to graduate students in mathematics to see if they'd enjoy devising puzzles for the community and to get any feedback they'd be willing to share on how the game's mechanics can better relate to higher-level academic concepts.' I had a desire to do this without my real name being attached to it, so I figured I'd respond via review.”
    • “But maybe this helps show that the theme (probably) wasn't chosen arbitrarily, but there were gameplay reasons for it.”

  • graphics

    3 mentions Positive Neutral Negative
    67% positive mentions, -67% neutral mentions, 100% negative mentions

    The game's graphics strongly embrace a calculator-inspired aesthetic, which adds to its unique charm. However, this design choice can make screen adjustments and navigation, such as using a graphing window alongside other applications, confusing and limiting for users.

    • “I understand the desire to maintain the calculator aesthetic, and it works strongly in the game's favor.”
    • “I understand the desire to maintain a calculator aesthetic, but it was confusing when I tried to adjust the game to fit half screen to use a spreadsheet on the other half, only to realize it would never fit.”
    • “I understand the desire to maintain a calculator aesthetic, but it was very confusing when I tried to adjust the game to fit half screen so I could use a spreadsheet on the other half, but realized it would never fit.”
    • “I understand the desire to maintain the calculator aesthetic, and it does work strongly in the game's favor, but I can't actually find the graphing window anymore.”
    • “The game owns its aesthetic.”

  • humor

    • “Funny math-based puzzle game.”

  • story
