A sibling duo playing nicely signifies either an answered prayer or a plan to frame a third sibling for shaving the dog. Occupy child pairs or inner children with today's Groupon: for $15, you get two wristbands that are each valid for three hours of bowling, go-karts, and mini golf at Strikes & Spares Entertainment Center in Mishawaka (up to a $29.90 value).

Strikes & Spares Entertainment Center delights thrill-seekers of all ages with a smorgasbord of family-friendly activities housed inside a massive, smoke-free center. Bowlers continue the battle against humanity’s bottom-heavy foes along lanes that automatically rouse bumpers for wayward rollers and digitally record the skirmishes' tallies on touch-screen monitors. At night, cosmic bowling bathes the alleys in a swath of black lights and a sheath of energetic music. Electric City's exhaust-free, environmentally friendly go-karts spin racers around two indoor tracks that divvy speedsters into regular and junior courses—entry dependent on age, height, and reflexes scored from a standard catch-a-live-chicken test. With nine holes, the black-light mini golf weaves putters along a course that diverts the glowing orbs with tricky angles and imposing obstacles. Though not included with this Groupon, gamers can fuel up with a full menu of burgers, pizzas, snacks, and drinks.

While prices and offers vary throughout the week, this Groupon still offers the best deal available.
