Stack'em 3d for Mac

: Beginners will often overlook a simple threat to score four; it is therefore important to always check all vertical, horizontal and diagonal possibilities before making a move.In a score four game in progress, one aims at forcing a win by making two threats simultaneously; conversely, one should prevent the opponent from doing so. As a general rule, discs played in the center columns are more valuable than border columns, because they participate in more potential four-Ball Lines (and accordingly limit the opponent`s score four opportunities).Among good players trying to score four, the short term goal is to Connect three balls, thereby preventing the opponent from playing in a certain column. Towards the end, the game then often turns into a complex counting match: both players try to score four by forcing the other to play a certain column. In these situations, it is useful to realize that, if it`s your move, then after filling an even number of places, it`s still your move. Every column has an even number of places.
