Refract Puzzle Game vs Counterspan

Bend the light. Find the path. Refract is a neon logic game about placing mirrors and watching a beam come alive. Route light through compact boards, illuminate every target, and find the cleanest possible solution. BEND EVERY BEAM • Drag mirrors from your tray onto the grid • Tap a placed mirror to rotate its reflection • Watch the full route update as you experiment • Undo a move, reset the board, or use a hint when you need a nudge • Light every target to complete the puzzle MASTER THE SPECTRUM • Solve 100 levels across 10 distinct worlds • Begin with simple reflections, then face blockers and checkpoint routes • Split one beam into multiple paths • Tint light at a prism, then prove its color at a gate that absorbs any beam that does not match • Carry beams through linked portals • Combine every mechanic in the final mastery worlds CHASE THE PERFECT ROUTE Every board awards up to three stars. Finishing earns the first. Solving within a comfortable move budget earns the second. The third asks for a clean run: inside par plus two, with no hints and without clearing the board. Taking a mirror back off the grid is always free, so exploring an idea and changing your mind never costs you a star. Only the moves you keep count. EVERY BOARD STAYS REACHABLE A level opens once either of the two before it is done, so a single puzzle you cannot crack never blocks the rest of the campaign. Worlds open on stars you have already earned. RETURN DAILY A featured challenge changes every day. Solve it to earn bonus coins and gems, then come back tomorrow for a new route. MAKE THE GRID YOURS Earn coins and gems by playing. Spend them on hints or unlock atmospheric board themes including Solar Flare, Arctic Prism, and Ember Void. Optional App Store purchases offer another way to unlock the same kinds of items. DESIGNED TO FEEL GOOD • High-contrast neon visuals, with light that visibly travels along the beam • Clean chimes for lit targets and solves, mixed so your own music keeps playing • Responsive haptics for moves, invalid drops, and successful solves • Colorblind assist gives every beam color its own distinct shape • VoiceOver labels and board actions • Dynamic Type and Reduce Motion support • Sound, haptics, motion, and colorblind assist all toggle in Settings • Portrait play designed for iPhone and iPad The full 100-level campaign is free to complete. Refract has no ads, subscriptions, accounts, analytics, or tracking. Progress and preferences stay on your device. Requires iOS 17 or later.

Counterspan is a single-screen truss load explorer. It shows one sample bridge truss, with eight joints and thirteen members, and lets you see how a load you choose is shared across its members. WHAT YOU CAN DO - Move the load slider from 5 to 60 tonnes and watch the readouts update. - See the truss drawn with its supports, deck and members. Members are colored by utilization, or you can switch the coloring off to see the plain structure. - Read the status (HOLDS or OVERLOAD) and the peak member utilization. With the built-in sample truss every load in the slider's range holds, at about 1 percent peak utilization. - Compare three readouts: the number of triangles in the truss, the material used, and an efficiency figure (load carried per unit of material). - Open the member inspector for a list of every member, sorted by utilization, with its length and axial load. - Reset the load to its starting value at any time. The sample truss is fixed. You cannot add, move or remove joints or members, and there is no campaign, level or score. PRIVATE AND OFFLINE - Works offline on iPhone and iPad. - No ads, subscriptions, in-app purchases, accounts, analytics or tracking. Counterspan uses a simplified teaching model. It is not an engineering tool and must not be used to design or check real structures.
