Frogger 2

The best level that I have found for this achievement is stage 2 Jewel Duel. The jewel will be in the middle of the screen so whoever is going for the achievement just needs to grab it and wait until you reach 100 points (each point equals a second). The level will end once you reach 100 points. Go for this while you are going for the win 5 Jewel Duels achievement. Repeat this 99 more times and the achievement will be yours.

Nobody plays this game and it's the least popular among all of the Frogger games released on the XBox Consoles. Personally in my opinion, if you want to get the online achievements done at a fast pace, I recommend you Double Box it with a Dummy Account. The reason is because if you decide to boost this with a partner, you will both have to take turns in winning, and this alone will increase the amount of time you both will be spending, playing online multiplayer.

The nicest advantage with this game is that if you own an XBox One and an XBox 360 Console, you can use the Share With Gold Feature, to give a Dummy Account the game on the XBox One, and you play as yourself on the XBox 360. This will prevent you from buying the game twice.

All of the online achievements in this game must be done in Ranked Matches. Player Matches "Do Not Count" towards your progression and you only need yourself and a partner/dummy account in order to get all of the online achievements done in the game.

For this achievement, you need to win a total of 100 Ranked Events. Any Game Mode you win on between "Jewel Duel" and "Race" will count towards the achievement. Personally, among the two game modes to choose from, I recommend "Jewel Duel" as it requires the least effort to gain the achievement.

Setting Up

From the Main Menu, you need to choose the following...

Multiplayer
Ranked Match
Create Match (Host) or Quick Match/Custom Match (If you are searching for the match)

Now if your the Host, here is where you get to choose the Game Mode, and the Stage. You can choose either "Jewel Duel" or "Race". It depends upon how skilled you are at the game. If you are good at "Racing", that game mode will be the fastest to get the achievement. If you choose "Jewel Duel", it's more Time Consuming, but you are guaranteed to get a win with little to no effort.
Once you have made a decision, you need to then choose a Stage. If you are playing "Jewel Duel", I recommend playing "Stage 2". If you are playing "Race", I recommend either "Stage 1 or Stage 2".

Once you have done that, you will be taken to a Lobby Section and this is where your partner needs to join. Once they have joined, you can press the button to start the match.

Jewel Duel Boost Method

Now the objective in this Game Mode is that of you will be fighting against each other to claim a Jewel that's placed somewhere on the Stage. Whoever grabs it will start getting Points. The first one who gets 100 Points, wins the match. You have a total of 10 Minutes. You would originally attack each other by pressing the button to steal the Jewel off them. And if you we're the one with the Jewel in your hands, you would run around the Stage and escape from your opponents to get the Points.

As you are boosting it however, only one of you needs to move to claim the Jewel. Once they have grabbed the Jewel, you just need to sit back and let the score tally up to 100. Then they will win the match. You do not get kicked in this game for idling. Your Frog will simply lie down and fall asleep.

Stage 2 will have the Jewel virtually in front of you, saving you the time and effort of rushing around the Map, trying to find the Jewel.

If you rinse and repeat this game mode and using Stage 2, it takes around about 1 Minute 45 Seconds to get 100 Points. And with setting up the Lobby/Match adding additional time, whilst waiting for your partner to join and start-up the match, it would take roughly 2 Minutes 30 Seconds - 3 Minutes per win. Therefore this would equal approximately 3 - 5 Hours per person to get 100 Ranked Match Wins.

Race Boost Method

Now the objective in this Game Mode is to simply Race against your opponent/s and be the first person to land on one of the "G" Goal Boxes on the other-side of the Race Track you are on. There are loads of obstacles, challenges and threats as you playthrough the Track, you must avoid. If you get hit once, your Frog will respawn at the Start of the Race Track, making you begin all over again. The first Frog who reaches a Goal Box, wins the Race. You have a total of 10 Minutes to complete the track.

As you are boosting it however, only one of you needs to move ahead on the track and complete the Race. You do not get kicked in this game for idling. Your Frog will simply lie down and fall asleep.

Whilst I would say Stage 1 & Stage 2 in my opinion would be the easiest for you to complete, it pretty much comes down to your personal preference. You may find another Stage in the game you would be better on, compared to myself.

If you manage to build up Skill on one of the Tracks in the game and able to complete it in less than 3 Minutes, add additional time towards setting up the Lobby/Match, whilst waiting for your partner to join and start-up the match, you may be spending a total of between 2 Minutes - 5 Minutes per win. Therefore this would equal approximately 2 - 6 Hours per person to get 100 Ranked Match Wins. Again for this Game Mode, it is skill preference.

Note: The game is known to glitch around with the online multiplayer side of the game. With this in mind, I recommend you work on all of the online achievements for this game in one sitting if possible

Tip: In the game, if you click on Leaderboards and check out your Score, you can determine how many Wins you need to get in total towards this achievement. In each Ranked Match you win, you will get a Ranked Score of 100 Points. So that's 100 x 1 = 1 Ranked Match Win. As an example, if you have a score of 4,500 Points, it means you have 4,500 x 1 = 45 Ranked Match Wins. Therefore if you want to know the exact score for 100 Ranked Match Wins, it would be 100 x 1 = 10,000 Points. So once you see your score nearby the 10,000 Point mark, it means you are closer towards the achievement.

Note: In regards to the achievement itself, only one game mode counts the total wins for this achievement all-together. This means that the achievement will not unlock unless you either have 100 Ranked Wins in Races, or 100 Ranked Wins in Duels. You cannot for instance get 65 Ranked Wins in Races and 35 Ranked Wins in Duels to make it 100 Total Ranked Wins. It's either one game mode, or the other.

Hope all this helps, Good Luck!
