***** #1 Puzzle Game in over 20 Countries! ***** ***** "This quirky puzzle game bends the limits of space and reality to make you create structures that, in theory, should be impossible to replicate." - Pocket Gamer 8/10 ***** ***** "As soothing as it is challenging, this grown-up puzzler opened our minds. Time flew by as we recreated sculpture after sculpture in increasingly difficult configurations. The game’s 3D graphics invite focus and sharpen problem-solving skills, making it an entertaining brain-builder. M.C. Escher would be impressed by the twisty, physics-defying structures." - App Store Notes ***** kubic is a unique optical illusion puzzle game based on M.C. Escher's art, impossible objects and other geometric designs. The object is to construct the goal configuration from a number of pieces. Presented in a simple, clean design and minimalistic art, kubic is a premium game with over 60 escher-esque puzzles. When you click on a piece, it pops to the front-most layer, and may overlap other pieces. When you combine the pieces, they do not merge. If there are extra pieces, you may hide them behind the others. You can also lock layers and drag pieces without changing their layer order. You can also use two finger pinch to zoom in and out and drag the view for a better control. If you are stuck on a puzzle you can simply skip it and re-visit at a later time. Rest assured, all puzzles can be solved but beware, some puzzles are hard! Just take your time...Tip: It helps to plan ahead and build figures from back to front. If you truly get stuck, there is a in-game hint system. You can use it to get started or even get the whole puzzle solved. Levels divided in 6 groups: • Ocean - "2D" Shapes are basically two-dimensional arrangements. • Desert - "3D" Shapes appear to be three-dimensional, but remember to think in two dimensions. • Mountain - "Convex/Concave" These optical illusions are inspired by Escher's famous "Convex and Concave" lithograph. • Sky - "Up/Down" These optical illusions are inspired by the Penrose Triangle featured in Escher's lithograph "Waterfall”. • Escher - Based on letter designs that spell out MC ESCHER. • Print - Based on the printable magazine version of Convex-Concave puzzles. Kubic is localized and supports 12 languages including English, French, German, Italian, Japanese, Korean, Chinese (simplified), Chinese (traditional), Portuguese, Russian, Spanish, and Turkish Game supports iCloud for progress syncing between devices. Convex Concave puzzles from the Heaven and Earth game are included with permission. The puzzles were designed by Scott Kim, Puzzlemaster (scottkim.com), and the Heaven & Earth team. Enjoy!
