LEVEL 1 : IMPROVING YOUR CONCENTRATION

At 8 cm the widest entry target is designed to offer a slight increase in difficulty. If you're lacking in confidence this level ups your concentration just enough to help rather than hinder.

LEVEL 2 : BUILDING UP YOUR CONFIDENCE

The second 7cm opening sets an increased challenge, try not to hit the sides. Look to hole an increasing number of putts without hitting the edges - once you're knocking these in without touching the sides you're onto a winner.

LEVEL 3 : VARYING YOUR PRACTICE

Level 3 sees the target reduced by nearly 50% in comparison to a standard hole, so aim to make over this percent of putts and you know you're well on your way to better scores.

LEVEL 4 : SIMULATING PRESSURE

The most advanced level. For most simply holing the putt through the 5cm entry point will be challenge enough. For the expert putters, the challenge is the highest number of consecutive putts - without hitting the walls if your name's Big Phil!
