Project Spark

Edit (5th October 2015): following Title Update 16, the original method of unlocking this achievement became invalid, and an alternate method was introduced.

NEW METHOD (after 5th October 2015)
Simply start the game on three consecutive days.

To ensure the game has registered your log in, wait until the main menu has finished loading and you can navigate around it before quitting out of the game.


ORIGINAL METHOD (no longer valid, but left here for posterity)

There are 20 squares on the Treasure Trove board. Each attempt at a match costs 1 Golden Ticket. Regular users earn 1 a day, Premium users earn 3 a day. You can also purchase them for real money too. You will need at least 13 Golden Tickets to guarantee making three matches in a row.

Premium users (earning 21 Golden Tickets a week) will be able to do this in one week.

Regular users (earning 7 Golden Tickets a week) will be able to do this in two weeks. Save your Golden Tickets for the first week, and earn this at the end of the second week.

When revealing squares, use a paper+pen to record which prizes are where as you work through the board. As soon as you have noted the locations of three sets of prizes, match them.

For the purposes of Treasure Trove, the week begins on Monday at 10am Pacific (USA), and each day thereafter begins at 10am Pacific (USA). You can use this website to convert 10am Pacific (USA) to your time zone. (Use USA/California/Los Angeles as the "Convert From" time zone.)

Note:
If you want to earn all but one of the Treasure Trove achievements - including this one - as quickly/efficiently as possible, I recommend saving up your Golden Tickets until you have at least 20. Regular users earn 1 a day, Premium users earn 3 a day. You can also purchase them for real money too. Simply logging into Project Spark earns you your ticket(s), just don't use it/them. You will also need to visit the Treasure Trove board each day for a week. Beginning on Monday and ending on a Sunday, in order to maximize the daily multiplier. Once you have 20 Golden Tickets, and (on a Sunday) the 4.5 multiplier; use them all in one go to guarantee you clear the board. Be sure to use a paper+pen to record which prizes are where as you work through the board.

edit (25th August 2015): updated solution to reflect new board reset days and times.

It looks like this has to be done in a single session, as I made a match Friday, Saturday and Sunday (only playing 1 ticket per day) and the tracker only shows 33%
