team razed must have had their reasons for using this color scheme. i think they're making it green = decreasing, but players can still play because it all depends on their luck.. and orange = increasing, but players should still be cautious and gamble responsibly. that's just my personal opinion. but team razed also includes up and down symbols, so players shouldn't be confused by this.
Therefore it would be better for gamblers to stay realistic and play without pressure and not to focus too much on RTP alone. Because in my opinion there is no guarantee that a high RTP will always provide a win. Luck-based games even at low RTP if you are lucky you still get a win.
Its somehow useful for gamblers to consider the RTP of the games they are playing.
But if they don't care much about it and just want to enjoy then still good since somehow we don't need to think on other things then gamble until they are satisfied with the result they get.
Also gambling still base on chance so even if they choose those games they think the best still we don't get any high guarantee that we could get more chance to win from those games we play. Sometimes I just let the faith decide if I'm going to win or not since I don't expect anything huge on gambling.
