Edgewise is a solitaire style game where players turn one card over at a time and place them into a 4x4 field. Once they add up to 10 they're removed. Once all the face cards are placed aroud the edges you win!  The site's instructions say:

Tap a card place to move the top card there. Face cards must be moved to a place with a matching label. Other cards may go anywhere.

Cards may not be removed until the board is full. Tap combinations of cards that add up to 10 to remove them. Face cards may not be removed.

Tap the deck to start placing cards again.

You win when all the face cards are in their proper places. You lose if a face card is turned up and cannot be placed. You lose if the board is full and there are no combinations of cards adding up to 10. 

Honestly, I was confused by this game. Maybe it's because I don't actually know how to play Mancala in the first place. But, I read about it for a bit, came back and played again and was pleasantly surprised. If you like Mancala aka Kalah you'll love this version.

Here's some info before you go play - http://en.wikipedia.org/wiki/Mancala

Phase 10 is a complex, engrossing card game from Magmic.  You can tell there was real care in making a high quality, fun game that has serious lasting potential.  If you like Rummy you're going to love this.  Magmic's instructions say:

Like Rummy, but with challenging and exciting twists!
Complete each of the 10 phases before the other players do.

Phases
Each phase has different requirements that you must meet, including runs, ses and 'cards of one color'.
- Run: a group of cards in sequence for example 3-4-5-6 or 9-10-11-12. A run can't go beyond 12. For example, you can't combine 11-12-1-2.
- Set: a group of cards with the same number value.
- Cards of one color: a group of cards with the same color.

The 10 phases are:

1. 2 sets of 3
2. 1 set of 3 + 1 run of 4
3. 1 set of 4 + 1 run of 4
4. 1 run of 7
5. 1 run of 8
6. 1 run of 9
7. 2 sets of 4
8. 7 cards of 1 color
9. 1 set of 5 + 1 set of 2
10. 1 set of 5 + 1 set of 3

Playing a Phase
To play a phase, you must place face up, all of the cards necessary to meet the requirements of that phase.
You must play entire phase in one turn.

Dealing
Each player receiver 10 cards. The remaining cards are the draw deck. The top card of the draw deck is turned face up to start the discard pile.
The player to the left of the dealer starts.

Playing a Turn
To start, pick up the top card from either the draw deck or the discard pile. If you have the right cards to complete your phase, you can play that phase. If you have already played the phase, you can hit any phase until you're unable to carry on. To finish a turn, place a card on the discard pile.

Hitting a Phase
To hit a phase, you add more cards to any phase that has already been completed, yours or an opponent's. You place face up, cards that also meet that phase's requirements:
- to hit a set, the card must be the same number value
- to hit a run, the card must continue the run in either direction (eg. if the run is 3-4-5-6, then place either a 2 r 7)
- to hit 'cards of one color', the card must be the same color

Wild Cards
A Wild Card can repesent any card in the deck. You can use Wild Cards to complete a phase, but remember that, in any group, there must be a least one natural card. For example, to complete a set of 3, you can place 6-Wild-Wild.

Skip Card

A skip card forces a player to skip their next turn. A Skip card can't be picked up from the discard pile. If you discard a Skip card, you can apply the "skip" to any player. If a player has to skip his/her next turn, you can't apply another Skip card to that player until the current skip has occured. If a hand begins with a skip card as the discard pile, then the first player skips that turn. Completing a Hand
The hand ends when a player runs out of cards. If you completed your phase, then for the next hand, you'll work on the next phase. If you didn't complete a phase, then for the next hand, you'll try again to complete the current phase.

Scoring
Any cards left in your hand, when the hand is finished, are added to your running total.
Card values:
- 5 points for card numbered 1-9
- 10 points for each card numbered 10-12
- 15 points for each Skip card
- 25 points for each Wild card

Winning
At the end of a hand, the winner is the player who completed Phase 10. If more than one player completed phase 10, the player with the fewest points wins. If it's still a tie, contenders break the tie with a new game of Phase 10!

Here's a funky and somewhat fun game that's similar to solitaire but with a twist.  The info on Apple's website says:

A solitaire game. Arrange all cards into 13 piles, so that each pile has 4 cards of the same rank. You can move a card to an empty pile or to a pile with less than 4 cards on it, if the top card of the destination pile has the same rank as the card you want to move.

 I liked this game but it took me some time to understand it.  If you like solitaire though you're going to love this.

This is by far the best game from myHip.  I really like RedDog since it's well made, offers hours of fun and revolves around betting and cards.  The objective is to bet that the drawn card will fall between the first and second ones in number or rank.  An example would be the first card is a 2 and the second card is an Ace.  In this case you'll almost definitely win unless a 2 or Ace is drawn in the middle.  That's just a simple example though so when you play be sure and tap the 'Show Rules' button so you can see the payouts and various rules.

The myHip game play instructions say:

To begin a round, the player places a bet (by hitting the "Deal" button) and the dealer deals two cards face up.

If the first two cards in a hand are sequential, the hand is considered "unplayable", then the player gets their bet back (a push).

If the first two cards are "playable", then the player can choose to play the hand as is, or double their inital bet.

When hand is played, the dealer shows the middle card, and if the card is between the other two cards (or makes a 3 of a kind when the first two are a pair), the hand is considered a winning hand. If the card does not fall between the first two, or if it is the same as one of the other two, then the hand is considered a losing hand.

Winning hands are paid out according to the payout chart shown in the table in the previous section.
