If you run out of boosters during your game, you can buy them for your coins. If you do not want to spend your coins on in-game boosters, pay attention to the number shown beside the booster. If the symbol of coin and price appears, you are out of boosters and can buy new ones only for coins.
If your friend has hidden the game from their timeline, they will not appear in your friends list in the game or on the map - even if they play the game themselves. In this case they cannot help you with the quests or receive your gifts as well.
If you are stuck to a level and cannot complete it, try to use boosters! You can use up to three 20s boosters per level. Highlight can help you spot tiles that are open. Every game has one free reshuffle - use it when in need! Superhint will hint a pair every three seconds. If you still cannot make it, you can buy additional time at the and of level to progress!
If you have trouble seeing the tiles, you can opt for a new set from the Market or zoom-in in your browser. If you are using large display monitor, try out the 'Large screen' option in the Settings menu!

The tournament is a real-time event against other players. The green coloured numbers in tournament leaderboard indicate that those players are actively playing in tournament. If you achieve position and leave the game for a while it is normal that you will be on lower position later, as other players have collected dragons while you were away.
