Drag along the floor. It fires on its own.

Answer 1. One finger slides the cannon and you never tap to shoot. The game's own floor says it: Drag to move.

What it is, the ads, the membership, what leaves your phone, and the cannons.
A ball shooter on the App Store. You drag the cannon along the floor, it fires on its own, and you split numbered balls down to nothing. Everything sold inside is optional.
No. Every level can be cleared, and every cannon opened, without watching one. A short ad can play between some levels and after some lost runs, and a small banner sits below the game. The optional ads continue a run, double a level's coins or today's crate, or pay for an upgrade when you're short of coins. No ads removes the breaks and the banner.
An optional auto-renewing membership, monthly or yearly, with both prices on its row of the coin door above. It renews until canceled in your Apple Account settings. No purchase is needed to clear any level or open any cannon.
The game needs no permissions to play. An advertising network serves the breaks between levels, the rewarded videos and the banner; an analytics service receives crash and level completion data; and a backend handles sign in and cloud save, only if you choose to sign in. Purchases go through the App Store. Tracking is asked for only at the first ad break, and the game stays playable if you decline. Notifications are asked for only if you turn on the daily crate reminder.
Collect up to 96 cannons, each with its own feel. Upgrade power, fire rate and bullet count, and max a cannon out to open the next one in its class. Every upgrade shows on the cannon, and a fully upgraded one turns gold. Bolt on attachments, pick a drone escort, and bring a loadout of single-use abilities into any level you like.
