Circuitry is a hands-on logic game that makes Boolean algebra, logic gates, and digital circuits easier to understand. Build circuits by connecting AND, OR, XOR, NOT, and other gates, then experiment with different inputs to see how signals travel through your design. Work through 22 progressively challenging problems to unlock new components. Then use Playground Mode to create and test circuits of your own. Features: - 22 logic-circuit problems - Interactive circuit building and simulation - 36 different circuit components - Playground Mode for creating your own circuits

"AI gives answers, but you have to build your own thinking." In the age of AI, the key skill is not writing code well, but breaking problems down well. RoboTrail uses code-free command puzzles to measure and train the thinking muscles behind abstraction, decomposition, simulation, and working memory. All content is free, supported by ads. Campaign Mode - 108 stages across 10 levels Move your robot to the star across 108 stages. Start with arrow (up) commands, then learn function calls (F1, F2, F3), nested abstraction, color conditions, and efficiency compression, step by step. - Levels 1 to 3: command basics, spatial simulation, and spotting repeating patterns to group into functions - Levels 4 to 6: code reuse with F1, nested decomposition where F2 calls F1, then full synthesis - Levels 7 to 10: color conditions, large grids over 6x6, tight slot caps that force compression, and a master ceiling Each stage is graded up to three stars: fewest commands for three stars, efficient for two, a clear for one. Challenge Mode - 36 questions across 3 areas Measure your coding thinking objectively. Each area is timed, taken one at a time. Every attempt records your score, grade, and solving pattern. - Simulation (8 questions): track rotation and movement in your head - Pattern thinking (14 questions): find cycles and generalize reusable groups into F1 and F2 - Abstraction (14 questions): nested functions and layered decomposition across F1, F2, F3 Each area analyzes accuracy, solving time, deliberation before the first move, and trial-and-error count. Six master-ceiling questions per area carry 2.5x weight to distinguish the top 1 percent. Challenge Modes - same stage, new constraints Replay any three-star puzzle in three modes: - Speed: clear within 30 seconds - Tight slots: slot cap cut by half, forcing function use - Perfect: solve with exactly the minimum commands Collect up to three medals per stage. Daily Challenge One curated puzzle every day, with a live count of how many cleared it. Build your thinking one problem at a time. What you get - An overall thinking score from 0 to 100 with a 5-level grade - Strength and weakness charts by area - A growth-trend graph by attempt, so progress is objectively visible - Solving-pattern analysis: careful, trial-and-error, or balanced type - Campaign stages recommended for your weak areas - Star distribution, total play time, and fastest clear records Who it is for - Elementary, middle, and high school students interested in coding - Parents who want an honest measure of a child's logic and abstraction - Professionals warming up before an algorithm interview - Anyone wanting an objective look at their own thinking patterns - A pre-assessment tool for gifted programs and coding academies Honest measurement Instead of exaggerated phrases like aptitude test or brain IQ, we use honest wording such as thinking measurement and grade calculation. We do not claim percentiles until enough data accumulates. Use your own growth trend as the benchmark. Ads and Sync Ads run as banners and occasional interstitials, with frequency capping to protect the learning flow, and non-personalized ads by default. Progress backs up through Apple GameCenter and restores with your Apple ID, with no sign-up required. Recommended age: 12 and up

Verdict

The call

The clearest difference is in-app purchases: Circuitry at none against RoboTrail Coding Brain Trainer's 1. Circuitry also leads on ads (none vs shown). RoboTrail Coding Brain Trainer's advantage is update cadence (every 5 days vs every 46 months) and device support (3 vs 1). On price and iOS requirement there is nothing between them.
