I've looked for posts like this but several are outdated. Many of the games have a 'sweet spot' that earns you the maximum sp for the least work.

Burrero basket: how the point system works is earned pointsX10 for earned subeta points. The maximum amount of sp you can earn per game is 25000, so you should stop at 2500 points in order to not waste time or resources

cybill sledding: the number that caps out the sp earned is 6750, but in order to avoid mistakes or preemptive ending, I would aim for 7000 which is only a couple of seconds away. The maximum number of sp per play is 10000

Matala's jewels: I haven't reached a cap for this one yet because I haven't gotten past level 8, but it's over 30000 sp. If you want to earn this money the fastest, I recommend using timed mode which earns you points faster but at a harder difficulty. If anyone knows the sp cap for this please reply!

Net gain: this one really isn't worth your time unless you have the patience of a saint. you only earn a few hundred points for five minutes of game play. Omen Raiders: ? I don't have an answer for this one, but playing through one or two levels doesn't get you a lot of sp.

Pirate Panic: ? Since it's newer, I haven't gotten far enough yet. If you have an answer let me know!

Spectrail: This one won't get you a lot of sp in a short amount of time, in fact it's only a few hundred at a time, but the prizes are fairly illustrious

Bug game: over 6000, risk of loosing money, however. Timblerig: starts at 6000 per round and goes up with the more times you succeed Ziara raceway: To get the max, you need to beat it on hard, the more lives left the better. it takes about 3 minutes. 20000+ Caliphs tomb: Don't bother sending score unless you win it, or you get significantly less, and it's a quick games. 20000 sp for winning

divine disks: Not only can it earn your active pet intelligence, it can earn a decent sum in a short amount of time. 5000-10000 sp depending how early you get it

Mystic spindles: takes an awful lot of time for only a few thousand sp. I haven't done the final levels, however.

Many of the other games are N/A. If you know the cap to these games, please share

As a side note, quests that will most likely earn you the greatest profit on them are: wizard, pete, cursed, and sometimes Saggitarius, but he is initially incredibly expensive. Library and quinten can get you rare items to sell, but rarely make you a tidy profit. The rest can be hit or miss.

Balloon Sweeper - easy 2K, Med 5K and Hard 10K. However, unless you spend a lot of time playing, you it might be faster to play several med games rather than the hard. Because you're first few moves are completely random, you end up having to restart several times before finding a playable game, you might end up wasting more time that way.

Blackout is worth a good amount of sp (its based on gird size) but you can only play once an hour.

Bones is not worth the time, unless you need achievements or want to earn some items.

Divine Discs - you earn 11,000-(1000*# of rows used to guess). Eg You get the correct answer at 5 guesses, you earn 6K. Its quick to play and there is no limit to the number of games you can play.

Item Scramble earns 100*# of letters in solution (including spaces), so "This item wins" 1400 sP. Plus you get 50K for winning the bonus round.

Mazes & Mahars, I love this game, but rarely play because it takes forever. Win or lose, you earn around 6000-14000 sP. Play it if you like the game, but the time you invest just isn't worth the sP.

Memory is paid out based on the amount of tries it takes you to win. 14-19 tries earn randomly between 20K-30K. Not sure the other outcomes because I usually win in that range.

Saheric Slide. 3x3 3K, 4x4 5K, 5x5 - not sure of max, you have to beat a certain time.

Subeku hard 15K

Tubular Tiles, 10K per game, any game. I usually play the Volcano level because it is the smallest board. Need to use the "cheat" keys, reshuffle a lot, but there is no limit nor penalty for doing so.
