Zap Attack! slot by Thunderkick has one of those zany alien-type themes rarely seen but notable ones include Barcrest's old Money Mad Martians – Cosmic Cash slot and WMS' pretty decent effort with Invaders From the Planet Moolah slot. So that's a humourous cartoon style and here we have 25 pay lines over 5 reels of 5 rows with the alien top pay at 10x bet, lowest value for 5-of-a-kind is 1x bet. Randomly expanding Invading Wilds can appear on all reels and offer up a 2, 3, 4 or 5x multiplier which is multiplicative and the most you can get is 3 Wild reels at 5x or 125x multiplier in other words. Single Wilds also appear and symbols can be stacked. Scatters in the form of TV screens appear on all reels.

These are triggered by 3 or more scatters on any spin and you get 7, 11 or 15 respectively for 3, 4 or 5. Retriggers are 3 for 2 scatters, +5 spins for 3, +7 for 4 and +9 for all 5. The enhancement is a meter on the right for the 4 medium-value symbols (not royals) and any top-paying Alien that lands carrying a red ray gun zaps the first symbol on the ladder. When 10 zaps have occurred, you get +1 spin and that symbol turns to the Alien on the reels, and the Alien moves on to the next medium symbol up the side. Of course, you want all 4 converted so you only have royals and Aliens and Wilds possible on the reels thereafter. It works like the bonus on Thunderkick's Pink Elephants slot and you still get the Invading Wilds in play which may expand with multipliers as in the base game.
Zap Attack! slot has a RTP of 96.15% and 96.44-96.48% if using the 3, 4 or 5-scatter trigger bonus buys if available to you. These cost 60, 125 and 250x stake respectively. The game is medium to high in volatility with a max win cap of 5,000x stake.
