In the Number Limbo, it's not how low you can go, but how confident you are in your own choices. In the end, this game can be referred to as simply a game of luck, but I'd like to share some advice I've picked up from some of the previous winners.
1. Stay consistent, but play smart. If you see that a set of numbers previously landed a high amount of guesses, guess in increments 5 above or below that number. Chances are that many will see the number to be the next to win if other players are afraid to choose it, and as a result spikes in the graph can happen in the same place from day to day.
2. Guess in factors of 5. Many players go the 40,41,42,43,44 route, which normally leaves out increments such as 45 or 50 out of the mix. This factor only increases the chances that this number will be picked fewer times, and as such will be more likely to win. Be aware of the spikes and drops, though.
3. If you see a number that previously won or had a low guess count, avoid it. Most chances many will pick those numbers in hopes that they will win the next day. The flaw that hinders that plan is that 5-10 other players probably have the same exact mindset.
In the end, lean towards the numbers that previously peaked, and avoid the numbers that had a low guess count. Be consistant, stay determined, and don't sway to fear, and you might end up winning first place!
