A unique calculator concept and fun math-friendly gameplay make this enjoyable, but thin content, weak replayability, poor presentation, performance problems, and difficulty spikes hold it back.
Enjoyable overall fun: A large number of reviewers simply describe the game as fun, good, or enjoyable. This broad positive sentiment appears across many clusters with low-specificity praise.
Unique calculator-based concept: The game's core idea of using varied calculators and limited button presses to reach a target number is widely praised as original and creative. Players enjoy the distinctive puzzle design.
Strong for math lovers: Many reviewers highlight the game as excellent for players who enjoy math, mental arithmetic, and brain-training challenges. It is frequently described as one of the best math-focused games available.
Challenging but rewarding gameplay: Many players find the game challenging in a satisfying way, especially when limited buttons and presses force careful planning. Clearing stages or runs provides a strong sense of accomplishment.
Fun roguelike puzzle game: Players consistently describe it as an enjoyable roguelike or roguelite puzzle experience that blends arithmetic with roguelike progression. The combination is seen as creative and well executed.
Lack of content and replayability: The game lacks sufficient content, variety, and replayability. Many find it repetitive and not worth returning to after completion.
Inadequate presentation and performance: The game suffers from poor graphics, repetitive music, and performance issues like overheating. It feels unpolished and lacks customization options.
Poor balance and difficulty spikes: The game balance is questionable, with certain operations (+, -) being overpowered compared to others. Difficulty varies widely, with some modes being extremely hard.
Game too easy: Many players report that the game is too easy, making it less engaging and reducing the incentive to continue playing. Some note that it is basic and can be won quickly.
Missing tutorial and unclear UI: The lack of a tutorial and poor descriptions make it hard to understand buttons and game mechanics. Many buttons are poorly explained, causing confusion.
Calculator-based roguelike puzzle gameplay: The game is consistently described as a roguelike or roguelite puzzle experience built around calculators and numbers. Players manipulate values with math operations to reach target numbers.
Math operations drive core mechanics: Core gameplay revolves around adding, multiplying, and using numbers to transform a starting value into a target number. Mental arithmetic is a key requirement.
Varied calculators with unique functions: Multiple calculator types, including an Engineering Calculator and a crazy calculator, offer distinct special keys and challenge modes. Each calculator poses different challenges.
Limited-use buttons and energy management: Buttons have limited uses and are destroyed when exhausted, requiring careful management. An energy mechanic tied to button presses adds another layer of resource planning.
Round-based structure with win condition: The game features quick round-based gameplay where players take turns. Winning requires beating 20 rounds in total.
Heating issues from poor code: Users report severe heating problems and attribute them to badly written code. This suggests significant performance optimization issues that can affect gameplay and hardware.
Steam Deck compatibility issues: Players report that the game does not work well on the Steam Deck, indicating poor compatibility with the handheld platform. This may limit accessibility for users who primarily play on that device.
Strong overall recommendation: Many reviewers explicitly recommend playing the game and describe it as worth checking out. The feedback is overwhelmingly positive with no conditions attached.
Good value for money: Multiple reviewers highlight the game as worth the price and a good purchase for its cost. The low price is seen as a key strength, especially considering the replayability offered.
Negative recommendation due to state: Several reviewers cannot recommend the game in its current state, citing an unfinished or underdeveloped condition. They suggest waiting for further development before playing.
Appeals to roguelike fans: Several reviewers mention that the game is enjoyable for players who like roguelikes, often combined with an interest in math. It offers variety and difficulty options that roguelike enthusiasts appreciate.
Requires strategic thinking: Some reviewers recommend it for players who enjoy games that demand a lot of thinking before acting. This suggests the gameplay involves planning and problem-solving.
Game completion: 4.5h.
Session length: 0.5h.
Players report initial fun that fades into repetitiveness and blandness, with missing tutorials for numerical operations and powers as early friction. A minority says the game is never fun, but the strongest direct evidence describes an enjoyable start followed by a drop.
Friction: Missing tutorial for numerical operations; Missing explanation of powers; Confusing mechanics such as dividing by zero and unexpected explosions; Repetitive graphics and limited buttons.
Unlock drivers: Watching Richard Waterson's tutorial explains confusing mechanics and prevents early confusion.
Math-Roguelike Devotee: Grinds long endless runs, optimizes number manipulation to resolve rounds in a single turn, and compares energy values and difficulty modes in fine mechanical detail. Motivation: The satisfaction of cracking arithmetic puzzles inside run-based roguelike runs and pushing endless mode to ever higher rounds. Stance: buy.
Early-Access Optimist and Roadmap Follower: Plays current builds, follows patch progress, and gives feedback on features and localization while accepting unfinished systems. Motivation: Being part of the game's growth and watching new content, features and languages arrive during early access. Stance: buy.
Budget Puzzle-Snacker Newcomer: Short casual sessions, learning the rules by trial and error, and hitting a mental-math and onboarding wall that limits progress. Motivation: A cheap, bite-sized math puzzle that fills short casual sessions without demanding long-term commitment. Stance: sale.
Frequent Balatro Comparisons: Players often compare this game to Balatro, noting similarities in random generation, escalating stakes, and strategic replayability. Some find it requires more mental effort due to its math-based approach.
Optimism for Future Updates: Many reviewers express enthusiasm for future updates, believing the game will continue to develop and improve. They look forward to more content and features.
Early Access Status Noted: Reviewers frequently mention that the game is in Early Access and anticipate further development and added features. This status is seen as a reason for potential improvement.
Unique and Cool Concept: The game's concept is frequently praised as unique and cool, standing out among other titles. This originality is a major draw for players.
Ongoing Developer Improvements: The developers have been actively making improvements since release, and communication with users is considered fine. This positive reception suggests good post-launch support.
