Getting the dice you want
To get the certain monsters you want (such as Holy Doll or Kuriboh), all keep selecting "New Game" at the title screen. Every time you start a new game, you get randomized dice. If you are unhappy with what you got, do it again until you get the desired combination of monsters.
Roll desired numbers
If you want a level (for example, 2), then put three level 2s a your selected monsters and roll. Most of the time you will get that number.
Symbols
You may have noticed that symbols may appear above a monster's level. There are three symbols:
Feather: Indicates that it is flying and can only be attacked by other flying monsters. It also can fly over other monsters, but unfortunately, other monsters can move under it. Monsters with this symbol use double the movement cost.
Tunnel: Indicates that it digs underground to move around, so it can move past other monsters.
Arrow: Indicates that this monster can attack a flying monster.
Effective attacks
Some types are super-effective to others.
Dragon is good against Spellcaster
Warrior is good against Dragon
Beast is good against Warrior
Spellcaster is good against Zombie
Zombie is good against Beast
If you are dueling a person who usually tries to summon a level 4 monster on his first roll, if you get a Time Wizard and summon it his monster will be destroyed.

Get Exoida pieces faster
You must have Seeker in free duel to get Exodia pieces. After about one fight, he may start giving you Exodia pieces. It might take more than one fight, or he might give piece after piece. It will require over twenty fights to get Exodia's head.
Good defense
This trick requires a Lord Of D. and any dragon.. First, put your dragon monster in front of your dice monster in a way that there is only on way to reach your Dice Master, though your dragon. Then, summon a Lord Of D. and block it off from other monsters. You now cannot lose.
Save the dies with good Crests
Usually you need a lot of movement or perhaps Attack or Defense Crests. When you are picking your dice, on the top are two blank squares. Pick a Crest that you would like to try to get. Then, choose "Set". On the bottom, the three squares should be filled in with dice. Those dice are the best ones of all fifteen in your pool to get that type of Crest with. Memorize all the Crests you will eventually need, then save all your valuable dice until later. After you extend your dice path to your opponent's Heart Points and are a few spaces away from the Die Master, or you are already there but need some Attack Crests, then you can roll your best dice to get what you want in time.
Level 4 dice
Play Joey Wheeler repeatedly in free duel mode after you have unlocked him from tournaments. After awhile, he will give you a Black Skull Dragon which is level 4. Keep playing him and you will get another, and yet another. You can then put all three in your pool and use them in duels.

Box In: Dimension 2 level 1 monsters
Make your Dice path get as far down the board as you can with two monsters. Summon more monsters until the tip of the dice path you made goes left and right as far as possible. This way, your opponent will not be able to dimension any monsters past a certain point. You now have a lot of free space to summon more monsters without worrying about them being destroyed immediately. This stops your opponent from making a dice path past where you want them to. Both players will have a "box" of their own territory.
Free duel mode
When you go to free duel mode, no duelist will be there. In order for a duelist to appear, you must face them at the tournaments. For example, if you want to dice duel against Joey, you must dice duel Joey in the tournaments and win. Then, finish the rest and get money to buy dice, or sell the weak dice you do not need.
