In the game, there are various forms of currency that one must manage. All of these currencies are generally linked to one another, with prestige and diamonds being the most valuable.
Time Blocks Edit
Time blocks determine how many hobbies and jobs you can do simultaneously. You start with 6, and the other time blocks can be acquired through achievements; every 4 achievements will provide you with 1 time block. You can get up to a total of at least 108 time blocks without the use of diamonds (previously 92). Hobbies require 3 time blocks each, but Jobs require different amounts of time blocks, depending on the type of job you want to work on. Additionally, the four different dates use between 3-6 time blocks temporarily while they run. If you do not have enough free time blocks for a hobby, job, or date you will be unable to perform the activity. For example, if you have 19 free time blocks but wish to do Hunting (which requires 20), you will not be able to do that job until you cancel other activities or retrieve another time block.
To have every job and every hobby active at once you need 197 for jobs and 36 for hobbies (233 total) at the most, and 81 for jobs and 36 for hobbies (117 total) at the least because the time requirements lower as job level increases. Note that either of these are impossible as you only can have 108 time blocks (without purchasing more with diamonds).
Cash allows you to buy gifts and go out on dates with the girls, both of which also provide affection. Girls will require gifts and dates to advance to the next level, a few will even want cash directly. The only way to acquire cash is through doing Jobs. Early in the game it is usually best to get the most amount of cash in the shortest amount of time. Later on, however, you will need to build up cash in order to acquire the cash achievements.
Affection, shown as a heart symbol, is the quantitative form of time and effort you spend with the girls. Affection is acquired primarily through the Girls tab, where you can chat, buy gifts, go out on dates, tap them, or even just wait (if you have their favorite hobby) all of which give Affection. Affection is required both for achievements as well as the primary requirement in advancing a relationship with someone.
The top button on the Girls tab will visually switch between "Sorry" ("Atone" in earlier versions), "Chat" ("Talk" in earlier versions), "Flirt" and "Seduce", depending on the girl's current relationship level. Each click will generate affection, and has a cooldown affected by the current prestige multiplier. The formula for hearts gained, obtained from Sad Panda Programmer and confirmed with lots of data from Nutaku, Kongregate and Steam, is: INT( (20 + LikedTrait^2) ^ (1 + GirlsAtLover / 6.5) ) (Spreadsheet). This active method, possibly augmented by an autoclicker, is preferred once all necessary gifts and dates have been obtained for a relationship level.
Affection is also gained through gifts and dates. Dates are more efficient than gifts but they take time blocks and actual time, plus higher level gifts give significantly more hearts than the highest level date.
Clicking directly on the girl, a.k.a. tapping or poking, but is limited by how fast you can click the girl (typical fast clicking is around 10 per second). The affection gained each click is equal to the number of girls currently unlocked, even if you haven't viewed their introduction sequence yet. The "* Poke *" graphic will appear when a girl is at maximum affection for the current relationship level. This active method is slow but is good when you're starting out in the early game.
Once you have at least one level in their favorite hobby, shown in-game on the girl's Stats display as "Liked Traits", you slowly acquire affection for that person over time; please keep in mind that affection earned this way does not apply to the affection achievements. The rate of affection is equal to the level of the girl's favorite hobby multiplied by the reset boost per 30 seconds. This passive method is slow for later girls and higher relationship levels, but it does have the advantage it is the only way to gain hearts without clicking, while working on another girl, or if you aren't playing the game.
Prestige is the formal name for your multiplier, which speeds up all time-based activities. This includes jobs, hobbies, chatting, gifting, and dating. Poking is also affected, as it currently has a cooldown. You gain prestige by completing achievements and raising relationship levels, but you must perform a soft reset in order for it to take effect.
As of Version V.0.94, the prestige multiplier (speeds up all cooldown, hobby and job times) is no longer capped.
Diamonds are the premium currency of Crush Crush. They can be used to greatly speed up hobby levels, purchase time blocks, skip resets, allow you to buy special outfits for a girl after reached Lover level, and serve as an alternative to cash.
The easiest way to obtain diamonds is through advancing to the next level with one of the girls, though they can also be bought with real money. They were also obtainable during the Easter 2017 Event.
You get 1 diamond when you get to a level with a girl you have not gotten to before (even if you got to it before a soft reset) and you get 3 when you get to lover level. As you do not get a diamond by unlocking a girl, you get 11 diamonds in total for each girl when completed. With 19 girls the total number of diamonds you should get is 209 (without buying any), however Pamu steals a diamond and apparently so do other girls so the total number of possible diamonds is unknown.
