RollerCoaster Tycoon/Leafy Lake

Leafy Lake is a fairly straightforward scenario. You only need 500 guests and you have 3 years to do it. You start out with a $10,000 loan, but can increase it to an outrageous $50,000. There is also more land to buy, but at $90 a pop, it's not recommended unless you truly run out of room. The park already has a path around a large lake, but there are no rides or guests. The first thing you need to do is delete a section of the path around of the lake near the far end so it is no longer a continuous circuit because this highly decreases the likelihood of guests getting lost. Avoiding circular paths is one of the keys to keeping the guests from getting lost and, in turn, unhappy. If you want to keep entire pathway, you can alternatively delete just two small bits of path and put them back when you have enough funds to cover the empty area with rides and stalls.

Start by placing trash cans near the benches to ensure trash has somewhere to go. Then hire three or four handymen and have their patrols set at a section of the lake. For rides, build a carousel or ferris wheel on the outer edge of your park as well as a Scrambled Eggs ride. The strategy is to let those rides build up your profit until you can build a roller coaster over the lake. Set up a couple of bathrooms, ice cream stalls, and drink stalls to keep the guests happy, but be careful not to set them near your future roller coaster's entrance. If you need more money, there is plenty of it available through loan, but if you start taking too much, you'll end up owing more than you earn a month. Take care to keep track of your monthly spendings and earnings.

Once your first roller coaster is up, you should have a decent flow of money coming in. If not, build a few more thrill and gentle rides or advertise to boost income and attendance. It's highly recommended to build along the lakeside path, but if there's not enough usable space, you can also branch upward to the north where there's plenty of space available for another roller coaster and some smaller rides. Make sure the path that's going uphill isn't too twisted to make it easier on staff patrols and tired guests. Another bathroom as well as a couple of food stalls should also be placed up there.

As long as you keep track of money and slowly have rides scattered along the lake's path, having the required number of guests and rating should be no problem. Given that the requirements for this level are even more lax than those of Dynamite Dunes, the real challenge here is waiting for the end of the third year to come.
