Hypersins works in the same way as coin-fraccing. To initiate the feature, you just need to press the Hi-Ins button. There are two types of hypersin: instant and multiplier. The instant hypersin doubles any coin payout, but the multiplier hypersin quadruples the payout. To activate the multiplier, you must also match a certain amount. At level 1, this is 3 Shamblers, so make sure to match at least that many.
