Here’s the English translation of your pachinko machine description with the specialized terms kept accurate to the industry:

The hugely popular anime Senki Zesshō Symphogear, which already boasts a strong pachinko fanbase, is now available in an easy-to-play Ama-deji (low-probability) version.

The initial jackpot probability is 1/99, making it more accessible. From there, there’s a 50% chance to enter Zesshō RUSH. While in Zesshō RUSH, the loop rate remains high at 70%, and on 10% of successful continuations, the Lucky Trigger mode called Chō Zesshō RUSH is activated. Chō Zesshō RUSH boosts the loop rate to 85% and significantly increases one-shot payout performance.

The machine is loaded with rich production customization features, including the hugely popular Japanese “Lever Vibration” (Rebaburu), where the center lever shakes to signal a high-probability win. Thanks to its easy-to-play specs, this model is highly recommended for first-time pachinko players.

I preserved terms like Ama-deji, Zesshō RUSH, Lucky Trigger, and Rebaburu in romaji with explanations since they’re unique to pachinko and not directly translatable without losing meaning.

If you want, I can also make a fully localized version for an overseas audience that replaces or explains all Japanese names inside the sentence flow so it reads like a press release for non-Japanese
