How many blocks? Look again. Some blocks are in plain sight. Others hide behind the stack. HIDDEN BLOCKS is a 3D block-counting logic puzzle where the real challenge is figuring out what you can't see. Study the stack, picture the hidden layers, and choose your answer. Simple to understand. Surprisingly tricky to solve. ▣ TWO MODES. TWO WAYS TO THINK. ● Count All Blocks Work out the total number of blocks, including the ones hidden from view. Every layer counts. ● Find Hidden Blocks Count only the blocks you can't see. Look beyond the visible faces and imagine what completes the stack. ▣ SMALL STACKS. BIG AHA MOMENTS. Start with simple shapes and progress to trickier, multi-layer structures. Use spatial reasoning to work out each answer. That satisfying moment when the whole stack makes sense? That's the fun. ▣ A FRESH PUZZLE EVERY DAY Daily Blocks gives you a new challenge each day. Take on the same daily puzzle as other players and see how your solve time compares. ▣ JUST FEEL LIKE A PUZZLE? Practice serves up a random puzzle each time. No stars, records, or rankings. Warm up before a stage or enjoy another little challenge. ▣ HOW FAR CAN YOU GO? Solve within the time limit, earn stars, and keep moving through the stages. Compare your stage progress with players around the world on the global leaderboard. ▣ A NOTEBOOK FULL OF PERSONALITY Warm paper, blue-ink answer marks, and three playful block companions give each challenge a little character. Clean puzzle layouts keep the focus on the blocks, while the Cubie trio brings the celebrations. Enjoy logic puzzles, visual brain teasers, or number challenges? Discover a different kind of block puzzle: count the stack and imagine what lies out of sight. ▣ WHERE THE IDEA CAME FROM Counting stacked unit cubes is a classic spatial reasoning exercise found in math curricula around the world — Common Core in the US, Singapore Math, the UK National Curriculum, and more. It trains the same 3D thinking that engineers, architects, and pilots use every day. HIDDEN BLOCKS takes that proven concept off the classroom page and turns it into a competitive daily brain game. There's more to every stack than meets the eye. #brain_training #spatial_reasoning #block_puzzle #logic_game #unit_cubes #3D_thinking #IQ #math_puzzle #puzzle_game #brain_game #hidden_blocks #casual_game #mind_game #focus #cube #counting #visual_puzzle #logic_puzzle #mental_training #block_counting

Challenge your spatial mind with Spatial Block, the ultimate 3D logic puzzle! Rotate and guide falling blocks in a 3D grid cage to clear complete layers. Combining classic block puzzle mechanics with a full 3D spatial experience, it offers both relaxation and a serious brain workout. [ How to Play & Controls ] Playing in 3D is simple and intuitive: Move Block: Swipe in the direction you want the block to slide (Left, Right, Forward, or Backward). Rotate Block: Tap anywhere on the screen to rotate the block horizontally on its Y-axis. Vertical Rotate: Tap the "ROT X" button to rotate the block vertically on its X-axis. 3D Camera & Inspection: Drag or swipe with two fingers to freely rotate the 3D grid cage and view from any angle—including directly from underneath—with seamless auto-snap back to the front. Keep Block: Tap the "KEEP" button to store a block and swap it later. Drop Block (Hard & Soft Drop): Tap "DROP": Instantly drops the block to the bottom (Hard Drop).
