How to play

The great news is that it’s easy to get started playing Jack in the Box. First, adjust your bet on the right-hand side of the screen by using the plus and minus buttons. When you’re ready to spin, you can hit the spin button located on the far right. Alternatively, hit the spacebar if you’re playing on a computer. It’s also possible to speed up the spin and skip through the animation by tapping the spacebar twice.

You’ll find the game’s menu on the far left of the screen, symbolized by a plus sign. Click here to adjust the volume of the music and sound effects and to read up on the rules.

Although relatively basic and cartoonish, the graphics for Jack in the Box definitely add to the game’s unique charm. The reels are set against a background of a classic circus exterior under a starry night sky with floating balloons. Symbols include a grinning lion with bright red mane (the most profitable,) an elephant wearing a party hat, a mischievous-looking bear, a clown’s cannon, a magician’s top hat and a box of popcorn.

The soundtrack features circus music and is quite understated, so it shouldn’t feel too repetitive even when playing for long periods. Of course, it’s easy to mute the sound if you prefer to play in silence.


The main game features include a “?” symbol that can appear anywhere, covering a wild or a multiplier. When the spin animations stop, the “?” symbol will disappear and unveil what’s hiding underneath. If you happen to land more than one “?” symbol during a single spin, all of the question marks will transform into the same wild or multiplier to boost your winnings.

The Jack in the Box wild is another notable feature that can appear as a 4×4 symbol over reels 2 to 5. It’s possible to earn instant prizes (between 40 and 500 credits) based on how many wilds appear during a single spin.

Bonuses and jackpots

The Jack in the Box bonus game is one of the most exciting parts to look forward to when taking this title for a spin. It’s triggered when two or more bonus symbols pop up anywhere on the reels. During the bonus round, you’ll need to open some jack-in-the-boxes at random to match three symbols. If you manage to do this, you’ll receive a special reward. The potential rewards that await include a cash prize of 15x your bet, up to 50 free spins and more.
