RobozzleReboot vs 101 Circuits

Robozzle Reboot brings back the classic robot-programming puzzle game to iOS — write tiny programs to guide a robot around a grid, collect every star, and reach the end. No syntax to memorize: every puzzle is solved by dragging instructions into place. HOW IT WORKS Program your robot with a small set of building blocks: move forward, turn left, turn right, paint a tile, and call one of five subroutines (F1–F5). Any instruction can be conditioned on the color of the tile the robot is standing on, so a handful of slots can express surprisingly deep logic. Run your program step-by-step or at full speed, and iterate until every star is collected. CAMPAIGN + COMMUNITY PUZZLES Work through a curated Campaign of puzzles from Robozzle's original creators, sorted by difficulty from your first steps to genuine head-scratchers. Or dive into Community Puzzles — the full catalog, searchable and sortable, with ratings from other players. BUILD YOUR OWN Design and publish your own puzzles with the built-in puzzle editor. Lay out the grid, place stars and colored tiles, test your solution, then share it with the community. TRACK YOUR PROGRESS Sign in with Apple to claim a pseudonym, appear on the global Leaderboard, and rate the puzzles you play. Earn points for every puzzle you solve, and pick up right where you left off — your progress is saved automatically. NEW TO ROBOZZLE? Start with the in-app Tutorials, a short series of levels that introduce each instruction one at a time. Robozzle is an original game by Igor Ostrovsky and other contributors (robozzle.com). Robozzle Reboot is a fresh implementation, built with the original author's agreement.

earn electronics by building circuits and seeing how they work. In 101 Circuits, connect components, inspect signals on the oscilloscope, and adjust your wiring to match a target waveform. Begin with batteries, resistors, and simple connections, then explore filters, transistors, amplifiers, logic circuits, and oscillators. See how a capacitor smooths a signal, how a transistor switches current, and how connected components shape a waveform. Each exercise has a clear goal: produce the required output signals. Different circuit designs can satisfy the same requirements, giving you room to experiment and understand the result. The built-in Learn library explains component symbols, circuit behavior, and connections through diagrams, formulas, and practical examples. Circuit guides help you understand the principles behind each exercise. Use Sandbox to create and save your own circuits. Change resistance, capacitance, supply voltages, and signal settings, then inspect their effects. Add LEDs, explore different connections, and put what you have learned into practice. Zoom into waveforms, inspect voltage and current, and use Undo and Redo to revise your circuit. Saved progress lets you return to your work and continue at your own pace.
