"Spinblox rules - It is so addictive and priced reasonably. You need to at least give this game a chance!!!" - SCW9 "Good game - Hours of entertainment. Worth every penny." - MT1000 "Wonderful. So Fun. I had played the web app version of this game at it was so much fun. The app version brings new special blocks adding a whole new aspect to the game. Its fun, unique and addictive and you can save your games, a major plus for people playing to pass a few minutes." - freetoremix "Good choice - This is a very addictive game. Good choice even for the price. It's worth it." - Tisha728 "=D - It's addictive! Wayyy better than the online version" - kgom "Worth It - This game is a mix of Bejewled and Tetris..." - ajkubert "Very fun and unique game - I bought Spinblox on a whim today, and I'm glad I did. Spinblox reminds me of tetris (it's very different, but the genre is the same), but it has a lot more depth to it..." - Twxz "Great upgrade - I was a big fan of the beta version, and love the new version as much if not more, the special blocks takes some getting used to, but it's a great way to vary the gameplay." - Roger P. Moore "Addictive game - I love this game. Used to play it all the time online. Great gameplay." - wquintero Spinblox is a fun and exciting classic falling block puzzle game for all ages. Drag three or more same color blocks in a row or a column to activate them. Activated blocks are removed when the next wave drops. Activate a special block by activating a block adjacent to it. Be careful, blocks can be de-activated. The game is over when the blocks reach the top. Good luck!

A mindful, relaxing puzzle game with 99 increasingly challenging, handcrafted levels. Simple to play but not so simple to complete! Immerse yourself in the soothing ambient soundtrack and focus on solving the grid. “Quite simply one of the most beautiful puzzle games I have ever played. The design is simple, yet aesthetically pleasing, and the soundtrack is a wonderful sonic wash that perfectly compliments the gameplay. The puzzles themselves are well pitched. The introductory rounds are small enough to lend themselves to both a studied approach or random tapping. They gradually ramp up the difficulty level, and with so many to work through, there is great value for money to be had." - an App Store customer from the UK. How to play: Start at the origin and tap the squares to light a path across the grid. There’s just one rule! The numbers scattered across the grid tell you how many squares you must light up around each one to solve the puzzle… and that’s where the skill comes in!
