Sword & Poker by Gaia is one of the most enjoyable games I have played on the iPod touch even if you do not play Poker all you need to understand is the strength of the poker hands to attack your enemy.
You need to redo some of the levels to get enough money so you can upgrade your health bar, purchase the strongest weapon, although I found the Morning Star weapon to be the strongest because if allows you to stun your enemies forcing them to miss their turn. You can also upgrade your shield although some enemies have a magic spell equip which causes them to take your shield to use against you.
Game Over you think now?
But no you are then given another further 10 dungeons to advance, these remaining 10 levels are very tough & the shops have some very powerful weapons inc the Excalibur Sword.
Start the fight & use Chaos to turn all the corner cards to Jokers, then just ensure you play Straight or Flush attacks, I found that trying to play a Full House attack resulted in a Four of a Kind attack instead which would not stun the enemy. When you have a lot of hearts in your playing pack press the heart spell to heal yourself.
Using this tactic you can easily get enough money to purchase the Excalibur Sword, also make sure you upgrade you health bar by purchasing improved bags.
With the Excalibur sword the End of Chaos fight is very easy because by using 5 of a Kind attacks you do 100+ damage and easily finish off Chaos for good.
I'm looking forward to playing the sequel Sword & Poker 2 to see what changes the developer has introduced in the gameplay. If you have not yet played Sword & Poker I can recommend it highly as one of the best gaming experiences on the iPod Touch.
