Connect 4 is a classic two-player game in which players take turns dropping different colored discs into a 7x6 vertical grid. The pieces fall straight down, occupying space within each column. The object of the game is to connect four of your discs, either horizontally, vertically, or diagonally, before your opponent. This version has several other games modes which are all similar to the classic one, but with a twist, and a challenge mode. Currently the game is listed at $0.99 in the Windows Phone Store.
Step 1: Complete the miscellaneous achievements
Complete the achievements that relate to winning on certain difficulty levels, challenge mode, and finishing with certain requirements. For the achievements that do not mention require a specific difficulty, play on EASY.
Step 2: Grind 1000 games
You need to play a total of 1000 games. There is a shortcut that can be used to grind. See the guide for the method.
Connect 4 is just that, Connect 4. It really just is not that fun to play this game against a computer that always makes the perfect moves. The extra game modes do offer more fun, but barely enough to warrant the price tag. While playing 1000 games is a chore, there exists a method to make this grind not that bad at all. Following the guide, you should be well on your way to completing the game in under 8 hours.
MISCELLANEOUS ACHIEVEMENTS (9 for 125
NOTE: For the achievements that do not require a specific difficulty, play on Easy. You can change the difficulty by selecting "Options" from the Main Menu.
The following 9 achievements are obtained by completing miscellaneous tasks within the game.
Everything in Moderation - 15
Defeat 10 NORMAL difficulty AI opponents.
See "Learn from the Best."
On a Roll - 25
Win five matches in a row against NORMAL or EXPERT AI.
See "Learn from the Best."
Learn from the Best - 20
Defeat 10 EXPERT difficulty AI opponents.
You need to win 10 games on both expert and normal difficulties, including 5 in a row. Winning can be quite a challenge for the normal player. Luckily, someone has solved the game (for their PhD thesis), making these achievements easy using an online solver, which can be found HERE
. Click PLAY and it will bring up a applet with the solver. Each vertical line in the program represents a column in the game. You can manually click columns of the solver to mark the move the AI has made. Use the "move" button to generate the move you need to make next. You will win every time using this solver. The "<" button can be used to go back if you make an error and the "<<" button will reset the solver for the next game.
Economist - 5
Beat the AI within 10 moves in a quick game.
Quick games are any games not in challenge mode. You need to win the game before playing a total of 10 of your chips. This achievement seems to be glitchy and actually would ONLY unlock for me in challenge mode. This is quite easy to complete within a few tries in the challenge located in the first column on the left at the very top called "Pop Roulette." Every four turns, a bottom chip will pop out and all chips in that column go down one. Try to line up three of your chips on the bottom row, then place chips on top of the opponents chips (so yours are in the second row) in the adjacent columns (see picture below). Basically you will then have a 2/7 chance of getting the achievements when a chip randomly pops out. Keep attempting this until it unlocks. This may also be possible in the challenge "Third Time Lucky" which is just a normal Pop Out game. I cannot confirm it working on this challenge, however, but in theory it should.
Genius - 5
Win a quick game in under 45 seconds.
Quick games are any games not in challenge mode. You just need to finish off the AI in less than 45 seconds. This is most easily done in the "Pop Out" mode using a similar strategy to that found above in the "Economist" achievement. Quickly set up a build similar to the one pictured below, then "pop-out" the bottom row chip so your top chip falls to complete the Connect 4. For the best chance, play your chips as fast as possible.
Crossroads - 15
Form two 'Connect 4' winning lines in a single drop.
For this achievement, you need to complete two scoring lines simultaneously with a single drop. This is actually required to complete one of the challenges called "Double Trouble." Use the following strategy mentioned by IEvil IMonkey. Put pieces in the bottom left and bottom right corners first. Then try to have them both meet, in an upward, diagonal line, in the middle column. Place the top of that triangle last. Try not to ever place a chip that would allow the AI to place one in either of those diagonals you are trying to fill (right below the diagonal).
This achievement is also obtainable in 2-player local multiplayer mode. Use the same method as above.
