Penalty Shooters 2 is a football penalty shootout and nothing else, which is exactly why it works. You pick a country and a club, then alternate: aim and strike your penalty by dragging, then dive to save the reply. Win the shootout and you advance through a knockout tournament.
Each round the goalkeepers get better at reading you, so the game becomes about not being predictable — a corner you scored with twice in a row is a corner that gets saved.
Drag to set direction and power, then release. Aim just inside the post rather than at the very corner, and vary where you shoot — the keeper adapts to repeated patterns.
Choose a direction to dive as the shot is taken. Watching the striker's approach angle gives a better clue than guessing, though the game keeps some randomness.
