The main reason Elevens HD stands out among other Elevens card games is the graphics. The interface design is very well done. When playing, the cards are laid out in a perspective 3D view, not the flat 2D top view. There are 8 different types of beautiful card sets to choose from. The game table has a quality felt-type look, with a choice of 7 colors. All these options can be easily selected by just tapping on the cards or background right in the menu. Very simplistic and thoughtful.
The gameplay is very smooth and responsive. Even if you tap fast, the game won’t feel sluggish. There are 4 difficulty levels to select, with the difference in total time allocated to clear a round. Easy mode has no time limit to cater for casual play. For every game, you play 3 rounds to score as many points as possible. If you manage to clear all cards in a round, you earn a bonus round to score more points. The bonus is not just a one-time thing, as long as you can clear the table, you will continue to get a bonus round. Another way to score big is to use chains of 4, 5 or 6 cards to add up to 11.
This game is OpenFeint supported, giving you 8 achievements to unlock and high scores to post. There is a statistics page to track your score, total chains of 4, 5 or 6 cards and the numbers of bonus rounds you managed to play. One more thing is that the game state will be saved if you quit halfway. You can resume from where you left off later.
Overall, because of the good graphic design and smooth gameplay execution, Elevens HD is no doubt an excellent choice for a card game.
