This is a 4-reel base game. On the reels there are numbers which are added into a 9 stage trail, with bonus on position 4. Reel wins can be exchanged for the feature after correctly gambling Hi or Lo. Exchanging from £10 upwards starts the feature with the super feature open. On entry to the feature, all four reels spin off and the player steps around a lapper. Cash, nudges, super feature symbols, spins, bonuses and mystery squares will be offered whilst on this lapper. A correct Hi-Lo gamble adds the square again. Nudges may be used when landed on or banked into a nudge pot. Lighting 4 super feature symbols activates the super feature. The super feature consists of a 52 position trail. In the trail there are features, win spins; reel blasts and cash pot squares. Reach the end of the trail to achieve jackpot.
