Find the blocks, fill with color and discover a hidden pixel-art picture! Each puzzle consists of a grid containing clues in various places. The object is to reveal a hidden picture by dividing the whole area of the grid into rectangular blocks according to the rules. Block-a-Pix are exciting logic puzzles that form whimsical pixel-composed pictures when solved. Challenging, deductive and artistic, these puzzles offer the ultimate mix of logic, art and fun while providing solvers with many hours of mentally stimulating entertainment. The game features a unique fingertip cursor which enables playing large puzzle grids with ease and precision: to create a block, press and hold fingertip on a clue, wait until cursor fills the square and start dragging to neighboring squares.

About

Code Monsters

Features
Read full description

■ Programming ideas, learned through play Code Monsters is a battle game where kids arrange instruction blocks to program a monster's strategy. Sequencing, loops and conditionals — the foundations of programming — are learned by building, battling and revising, not by reading explanations. - Step-by-step lessons introduce one idea at a time - Kids try sequencing, loops, conditionals, multiple rules and enemy-state sensing - Watch the result, revise the strategy and try again. Iteration becomes part of the game. ■ Build a strategy, then watch your monster battle The blocks use kid-friendly labels with icons. Once the battle starts, there are no real-time controls. Win or lose, the result comes from the strategy your child built. What happens when "move closer and attack" is not enough? "If the enemy is charging, guard." "Move away, then shoot." "If HP is low, heal." By changing the order, loops and conditions, kids can discover their own way to win. ■ Collect and grow your monsters - Monsters learn new skills as they level up - Stamp memorable "it worked!" moments - Earn titles and customize monsters with coin-based skins ■ Fresh challenges every day - Today's Task: a rotating set of daily puzzles with coin rewards - Today's Challenger: a daily battle against an official work or a community creation - Share strategy codes and browse the gallery to learn from other players - Start by copying a strategy and changing just one thing ■ For parents - Designed for ages 8+, with a planned 9+ store rating - Battles play automatically. The main activity is thinking through the strategy, not fast tapping. - There are no ads in the app. - In-app purchases are coin packs for cosmetic items only. - Coins are only for customization. Power cannot be bought. - Public gallery posting is protected by a parental gate.
