• There is no time limit, so no rush. Think one step ahead if you have to face a difficult move. It might be your last one.
• Try to place classic and woody blocks on the board to destroy lines or 3x3 squares with every move in order not to fill up the board.
• Find your zen by balancing between destroying figures as quickly as possible and getting as many combos and streaks as you can to score higher.

Good App but a few suggestions

I like almost all the features yet from a potential standpoint I think a few additional features are necessary to make it a truly A1 app. One change is to allow you to disable in settings the ability for it to glow before you place the block down so you don’t know how your decision will affect the turn. Another more important feature would be to save states. For example, if you added a third game mode for practice you should allow the ability to move backwards in plays and the only way to do so would be to keep track of the states whether that is through an array or otherwise(stack) this could even be implemented as a setting features on any game mode or in a premium version as it would be a crucial tool for learning from your mistakes!

Edit: In addition look at A* search or Greedy algorithm to create a system of which blocks you generate for the turn. This should allow to integrate a difficulty setting into the game because you will know which blocks produce the most points and you can if let’s say they choose hard difficulty make sure it’s only giving them the blocks that only fit into one particular spot on the board.

Highly addictive , Highly frustrating

While I love this game for the simplicity and challenges, I’ve also grown a deep hatred for it. For starters, 5 long tiles? C’mon now... I have had certain games where I’m on fire till my next set of moves require a 2x 5 long tile, 4 long diagonal tile and completely just slaps my ego to the ground and constantly stomps it to the ground with its size 24 boot. I wish we were given the option to rotate or maybe just re-roll a new set of tiles (Please don’t add this as an in game purchase-able refill type option). I love this game and think its awesome through & through, but it’s just so frustrating when i know my move sets are perfect but get hit with such obscurely difficult tiles. Anyways, hope to see some updates soon cause this game is great. Hate to see another phone shaped hole in my wall because of the inability to change the outcome of such a great round ruined by that obnoxious 5 long, 4 diagonal, C/U (Backward/upsidedown) shaped tiles.

Random or pre-determined?

I downloaded this game because it looked like an interesting and challenging puzzle game. While those things did seem to be true at first, it seems as if the tiles you receive are not random as the developers state. When I first started playing, I was able to achieve multiple games with scores over 1000. Now, I can not even come close to achieving that. It would be blasphemous to assume that my strategy/skill at the game has decreased, so what exactly is the reason for this? While it could be purely coincidence, I would bet that the developers purposefully created the game in such a manner that makes it essentially impossible to top a player’s high score. I have come to this conclusion through not only my experience, but the experience of other reviewers. By intentionally making the game more, players will play the game increasingly more in order to beat their high score. The more people play, the more ad revenue the creators collect. While I cannot be certain in my assumption, I am confident that this is the case. It seems unethical and, quite frankly, pathetic. The concept of this game is awesome, and I commend the developers for that. However, I refuse to overlook this stain on what is an otherwise very-well created game. I would love to hear back from the developers about the perceived randomness of this game.

Hello! Thanks for your feedback. We're sorry if there was any confusion about our game. The shapes you get are random. We don't increase the difficulty of levels on purpose. You need to think one step ahead if you have to face a difficult move. If you have any suggestions or ideas on how to improve our app, please let us know at We'll be happy to hear from you and make our app better!
