Missions are tasks that give an extra opportunity to earn coins and stars for solving puzzles. The list of missions updates regularly and every time you will see new and interesting missions - complete them and get rewards! For completing 8 missions from the list, you'll get a special prize - a treasure chest full of coins or stars!
Missions vary in difficulty and duration, eg. some missions require solving puzzles with rotation and with a certain number of pieces. With regards to duration, there are missions that can be completed only within a short period of time, others last up to 3 days.
The available missions are displayed on your collection page under the packs:
Usually, there are 4 or fewer missions displayed, but if more missions are available at the moment, you'll see the button 
below the list of missions. Click on it to see the full list.
To start a mission, press the Play button next to it.
Please note that a puzzle/number of pieces/rotation will be chosen automatically and can't be changed. The progress bar under the mission will update as you complete the task.
There is a Daily mission on the list of missions. This mission requires completing two puzzles of the current day - a regular daily puzzle and an extra (bonus) daily puzzle. These puzzles are from the current monthly pack.
Note: missions become available only after you complete the first 5 puzzles. If you are new to the app/if you reinstall the app/if you change a device, missions will appear after you complete 5 puzzles.
I am unable to play missions anymore.
This is the third bi have asked this question and still have not gotten a workable answer. I am not receiving awards no matter what puzzles I play. Some times the program completely freezes up after a puzzle is finished. Cannot close puzzle,start another one, have to turn program or computer off. Please give me a complete and correct answer.
