Frogtastic is a marble-shooter in the Zuma tradition: a chain of coloured spheres advances along a track toward a hole, and you fire marbles from a frog in the middle to make matches of three or more before the chain reaches the end.
The pressure is constant because the chain never stops moving, and the strategy is in setting up chain reactions — a well-placed match can trigger several more as the gaps close.
Yes — the same format of firing marbles into an advancing chain to make colour matches before it reaches the end.
Place a match where clearing it brings two same-coloured sections of the chain together, so the closing gap triggers another match automatically.
Yes — tap to aim and fire. Nothing to install.
