Below are 16 cards. There are four cards from each suit: diamonds, clubs, spades, and hearts. The cards are arranged in a four-by-four grid as shown below, and four cards have already been put down.
Arrange the remaining cards so that each vertical column, horizontal row, and diagonal line of four cards contains one card from each suit. Tap a space to place a card there or to change a card's suit.

Below are 16 cards. There are four cards from each suit: diamonds, clubs, spades and hearts. The cards are arranged in a 4x4 grid as shown below, and four cards have already been placed down.
Arrange the remaining cards so that each vertical column, horizontal row and diagonal line of four cards contains one card from each suit. Touch a card to change its suit.
Let's start by seeing if we can't dig up a few hints to work from.
There's a card on the table that belongs to the row the heart is in, the column the club is in, and the diagonal line the diamond is in. Therefore, you can safely conclude that this card in question must be a spade. This is the kind of logic you'll need to use to solve the problem.

What card do you suppose belongs in the bottom-left corner? The column this space is a part of already has a diamond and heard in it, and there's a spade to the immediate right of it. Taking the above into consideration, we can conclude the card in question must be a club. Knowing this, we can also fill in the last card in the leftmost column, which has to be a spade.

Need another hint, do you? OK then, here's a good one. The card at the top-right corner is a spade, and the one at the bottom of that same column is a heart.
The rest of the solution is up to you, but it shouldn't be too hard to figure out.
