A relaxing number puzzle where you merge hexa blocks, build bigger numbers, and clear the board. Number Stack - Clear Hexa combines number matching, stacking, and merging on a colorful hexagon board. Match equal numbers, create bigger blocks, and plan your placements to keep the board clear. MERGE HEXA NUMBERS Place number blocks on the board and look for matching values. When equal numbers meet, they merge into a bigger number. Keep useful numbers close, create new combinations, and look for opportunities to make one move lead into the next. The bigger your numbers become, the more carefully you need to manage the space around them. CLEAR THE BOARD Your goal is simple: clear the blocks and keep the board under control. Every placement changes the board. A move that creates a merge now can also affect the space you need for your next block, so think ahead before committing to a placement. A well-planned merge can open space and give you another chance to continue the stack. BUILD BIGGER NUMBERS Start with smaller values and combine them into larger ones. Watch your numbers grow as matching blocks merge. Look for efficient combinations instead of making every possible merge immediately. Sometimes the best move is the one that keeps more options open. STACK WITH A PLAN Every block takes up valuable space. As the stack grows, placement becomes more important. Keep useful numbers together, avoid blocking future combinations, and leave room for the next blocks. The puzzle is easy to learn, but finding the cleanest sequence of moves takes planning. HEXAGON BLOCK PUZZLE The hexa board gives the number puzzle a distinctive way to arrange and connect blocks. Colorful hexagon tiles make numbers easy to read while keeping the board clean and focused on the puzzle. SATISFYING MERGE CHAINS One good match can create another opportunity. Set up your numbers carefully and watch a successful merge open space for the next move. Chain reactions turn a simple number match into a satisfying sequence. CLEAR EVERY LEVEL Progress through levels and solve new boards as the challenge grows. Each board asks you to manage your space, find useful matches, and decide where the next number should go. Take your time and make each placement count. USE POWER-UPS When the board becomes difficult, power-ups can help you create new opportunities. Use them when a crowded position is blocking your next merge or when you need to open space and regain control of the board. EASY TO LEARN, HARDER TO MASTER The core rules are simple: Match numbers. Merge blocks. Build bigger numbers. Clear the board. The challenge comes from planning ahead and managing the space on your hexa board. Number Stack - Clear Hexa is designed for quick puzzle sessions, but the growing stack gives you plenty of reasons to think about your next move.
