Let’s talk about how Stern Pinball fixed the biggest design problem in Pinball: The 𝐌𝐮𝐥𝐭𝐢𝐛𝐚𝐥𝐥 𝐌𝐨𝐝𝐞.

Pinball builds escalation into its game design through the use of upgrades and special modes unlocked during play. Players accomplish objectives by making specific shots, often somewhat risky, building up to a game state change that massively increases scoring potential – and often changes the shot targets on the field.

Those lights on the pinball field aren’t just for show, they point you to the active shots you want to hit to progress your modes and score your Jackpots. Lit shots change regularly throughout most games.

The most exciting special modes are Multiballs. When unlocked, the Machine releases extra pinballs onto the field. This is the most intense and obvious form of special mode, because the time between each shot you need to make shrinks significantly and there’s a lot of chaos on the playfield as balls collide. You can’t easily keep your eye on the ball, because there’s often 3 of them!

However, this also gives the player an additional sense of safety, as each extra ball is an extra lifeline. You only lose once every ball in play has drained, so while you’re much more likely to lose them in multiball, you also have more to lose.

This made the mode popular with players, but there’s an optimization problem. While new players liked chasing the chaotic experience for its own sake; as they gained experience many felt obligated to try and reduce the chaos in pursuit of higher scores.

Many players started trying to “cradle” some of their balls on one flipper, carefully controlling these balls as extra lives to focus on one ball at a time. This turned the chaotic fun into carefully shuffling balls from one flipper to another, using microflips and similar techniques to try and keep their “extra lives”.

This was rational, and emotionally valid – because nothing sucks more than unlocking a cool mode and then instantly losing it as chaotic shots drain the extra balls faster.

Stern Pinball‘s modern machines often attack this problem directly: by using a generous Ball Save timer combined with extra scoring opportunities during time-limited modes. For ~20-30 after unlocking a multiball, any ball you drain gets redeployed.

Combined with boosted scoring opportunities during time-limited modes, this safety valve flips the incentives! Why carefully trap balls when ball saves are free? This is the timefire off shots as fast as possible, aiming for the mode’s riskiest jackpots!

Once the timer is over you can cradle up and try to preserve the balls if you like, but you still get all the beautiful chaos of a Multiball when you unlock it.

Stern isn’t the only studio to do a generous Ball Save timer with Multiball, but it’s a standard on their machines for good reason. It’s an excellent, conscious solution to an incentive-alignment problem. Great system design.
