Here are a few tips for surviving this Garden of Eatin':
• Learn your footwork, or your scalework, or your slither..work...?. Anyway, a cool trick is wiggling back and forth in one place to lure a snake to its doom. Just press the left/right, or up/down keys back and forth. If you do it fast enough, you can make an 8 segment snake one segment long.
• Shrink the enemy snakes by eating them from behind until they're smaller than you, then you can turn the tables, eat em head on and gain length.
• Length - Length is a very tricky subject. The beginner might think that length is vital to killing enemy snakes. While extra length is never a bad thing, size isn't all that matters. Especially in the later levels, you will need to do a bit of munching even before you can attempt to bite another snake's head off. If you're already on the other snake's tail, it isn't too difficult to take a nibble out of 5 segments instead of 2. And in the meantime, there will be plenty of food and other eggs lying around so your snake will grow in no time.
As long as you don't die, you're in no trouble. Length is a lot like money: Easy come, easy go.
• Levels - All levels can't be played in the same way. Certain levels have distinct features (such as an open center, or long corridors) that need to be taken into account. Some parts of levels are more dangerous than others. If you take an objective look at each level and make a note of where you die frequently, or where you find good snacking opportunities, your game will improve tenfold.
• Eggs - Eggs represent the sole way you can increase your life total. No matter how good of a player you are, there comes a time when there is nothing you can to escape death. Protecting your eggs is one of the most important things you can do to ensure a healthy eating environment.
Build up lives in the early levels. Once you've almost cleared a level, wait until your snake lays an egg before you clear up that last enemy snake. This strategy needs to be played with both the bonus clock in mind, and the fact that you lose a segment when you lay an egg.
At times it may seem that egg laying is purely random. It is not. There is an egg timer that keeps track of when you are due for your next baby. This timer continues ticking between levels, so you don't need to worry about "missing" an egg. The timer does reset, however, when your snake is born, and when the bonus timer runs out. For this reason it is important to continue a reasonable pace through the earlier levels, or else you might run out of steam when the eating becomes challenging.
• Smart Snakes - For novice snackers, smart snakes can be a huge challenge. They can serve to be huge pests, and daunting enemies. Their movements might seem like they are always one step ahead of you, but they have one major disadvantage: They are predictable. Given the right conditions, they will always make the same moves. It would be well worth your while to spend a few games getting acquainted with their playing style.
One useful technique is the "sacrifice" where you lurk in waiting behind a wall (even a 1 tile wall will do if you get good at it!). When you lure the snake down the alley he is committed to his path, and then you use your speed advantage to nibble his behind.
