Random not always best

I love the idea of the game but I think the experience and strategy side of it could be enhanced.

1. Random piece selection by the engine makes life difficult because there are so many pieces so you can’t build with the expectation of a specific shape coming up because the odds are too low. Some shapes are more difficult to play with so this could be improved by keeping it random but tilting the probabilities away from the tough pieces slightly and towards the easy pieces.

2.. also random means you can get the same shape twice or even (rarely) three times. These can be extra difficult to place. The engine could only be able to pick a shape once in each three piece cycle.

3. Finally it is possible to go multiple turns where line or box creation is simply impossible. A lovely board can turn ugly in three turns. The engine could randomly decide if this each turn will be a normal random turn or if it is a ‘friendly” turn where some combination of the pieces on offer will form a line or box if you look hard enough to find it.

The game is great and I would like the current version to remain as an option for “totally random play” but I suspect that the above tilts would maintain the integrity of a random tile selection process but shift the game more towards the use of tactics and skill and away from dealing with the random slings of fate.

My favourite iOS game right now

This game is so addictive and one of my favourites by far. I’ve been constantly playing lately competing with my friends to beat each other’s score. The game is truly amazing. One suggestion though could you maybe add a coin system where the certain score you get you earn a coin. And you can use a certain amount of count like 100 for example to rotate one block. There have been some occasions where if I just had the option to rotate I could open then board for another move. Overall one of the best iOS games I’ve played!!

A salty experience

You have a sudoku tile map, 9x9 and each turn you get 3 shapes to put together to get rid of them. However, you can’t plan because you don’t know what is next and you can’t strategise a pattern because you cannot turn shapes. In fact you get your 3 pieces of shapes and the best you can hope for is to get rid os something leaving odd tiles everywhere. This would be fine if you could actually do something about it but you are literally stuck with what you get given. But it doesn’t end there. Instead of randomly selecting shapes, you begin the game with single, double and triple size pieces which you can stick anywhere with little effect and then as soon as you have created spaces to fit things like a left corner, it then gives you impossible pieces only such 3 right corners or lengths that 5 pieces long when there isn’t space for it. A clever puzzle will make it hard, a dumb one will make it impossible. Often this game gives you 3 pieces of which none are even usable. Game over.
