If you can devote about 30 minutes a day to playing games on Neopets, you can easily become a rich player. My advice is as follows:

• Cliffhanger - Use solutions solutions here. Be sure to play on Hard. Daily NP (Max): 1500
• Extreme Potato Counter - If you can count, play this game. Don't submit your score unless you have a 43 or better (not hard). Daily NP (Average): 900
• Kiko Match II - The trick to this game is to use your fingers. Once you get to the hard levels, pick any Kiko and point to it on your screen (with your finger). Make note of its color and background color. Quickly flip through all the other Kikos until you have your match. Do this and you will easily earn a TON of NP. I'm keeping the points low here, for the sake of saving your time, therefore, do not submit unless you have at least 170 points. Play three times a day. Daily NP (Average): 1020
• Meerca Chase - This game is just plain old easy. Play on any difficulty level you want, three times a day. Don't submit your score unless you have at least 200 points. Daily NP (Average): 600
• Whack-A-Staff-Member - One of the easiest games on Neopets! Play it three times a day and don't submit unless you have a score of 600 or higher (it isn't that hard). Daily NP (Average): 900
• Faerie Crossword - For 600 NP a day, there is no reason to not play this game. Guild Forum posts the answers to the crossword daily. Don't play unless the answers for today's date have been posted on the site. Use those answers to solve the crossword each day. Daily NP (Max): 600

This means, if you do everything I just told you, you will make 9870 NP a day.

Another you might consider playing are Tug-O-War (I generally win between 900 NP and 1000 NP, but this is very hard, so I don't expect you will do the same). Play it three times a day.

For a quick 150 NP, be sure to play the original Potato Counter. All you have to do is view the source of the page, find the hidden HTML form variable "p13" and copy its value. Take that value and enter it in the Potato Counter field, and you win an easy 50 NP. Play three times a day.

Freebies

Anything you can get for free is well worth it. The Snowager is the greatest free-item giver available! The current Snowager times are:

6-7am NST (9-10am EST)
2-3pm NST (5-6pm EST)
10-11pm NST (1-2am EST)

Visit the Snowager as often as possible each day. Once a day is fine though. Assuming you visit him once a week, you should get at least 2 rare items. Use the Shop Wizard and determine a good selling price. Sell the items for a fair amount and put the profit in the bank. Estimated NP per week (most likely MUCH more, but I'm being conservative here): 5000 NP

You should also do these things every day:

• Visit the Fruit Machine
• Visit the Giant Jelly
• Visit the Healing Springs
• Visit the Desert Shrine
• Visit the Giant Omelette
• Visit the Tombola

Spending

The trick to saving money is NOT SPENDING IT. If you are an experienced Neopets player, you know that buying food is simply a WASTE OF MONEY. Your pet does not need food to survive. You can go to the healing springs. You only need food for the Battledome, and you shouldn't waste your time there...yet. Do not buy ANYTHING, you don't need ANYTHING.

Selling

If you have a broadband connection to the internet, an optical mouse and a fast computer, buying and selling certain items can be extremely profitable. Certain items can be bought from Neopet stores at restock time and resold for ten (more more) times their value. A great example is Faeries - I used to buy 10-20 Faeries a day at 300-400 NP and sell them in my shop for 3000 NP. My daily NP from selling JUST Faeries was about 54000 NP. 54000 NP A DAY! My suggestion to you is find items that everyone needs but are not readily available and stick to buying and selling that specific item. You will be a millionare faster than you think if you continue to do this.

Another idea is if you ahe items you want to sell and you are checking the price and you see a item spriced for about 100nps or more below the selling price buy it and sell it for the selling price.

Employment

Basic Jobs available at the Employment Agency are insanely easy. The jobs are refreshed every hour on the hour, and 10, 20, 30, 40, 50 minutes past the hour. Be sure to be on the Basic Job page when the refresh time rolls around. The best way to get a job is to quickly click "Next 10" a few times, and scroll very quickly through the jobs. Look for easy items (do not pick ones you have never heard of) and glance at the "Base Reward." The higher the base reward the better...most of the time. Once you have a job, complete it as fast as possible. The faster you finish the bigger the bonus you get. Daily NP (Average): 5000 NP

Overview

By following this guide every day, you will earn this much money:

30 days x 9870 NP a day (games) = 296100 NP
30 days x 5000 NP a day (jobs) = 150000 NP
4 weeks in a month x 5000 NP (snowager) = 20000 NP
MONTHLY TOTAL: 466100 NP

Follow this guide for THREE MONTHS and you will have 1,398,300 NP

Be sure to have a bank account to keep your money in. The interest you will accrue from having this much money is tremendous. Collect interest daily!
