Alien Invaders Free Demo: the Marked-Row Build We Logged
The public Pragmatic Play demo of Alien Invaders runs inside this page, free and without an account. Our 2,798-spin session ran on exactly this build, marked row, counter and all, so the numbers in the review can be checked against a live board. 18+ only.
The demo, in the page
The demo starts on a 100,000.00 balance. Our session never moved off a 2.00 stake, the one every value on the rules page is quoted at. The dark bar's right-hand button fills the window with the board. If nothing appears after loading, the build is blocked in your region, and the contact form reaches us.
How to read the marked row
Only the bottom row pays. The reels change height from spin to spin, symbols cascade down into the row, and three or more of a kind sitting on it are what the game counts. A win multiplier opens every spin at 1x and climbs by 1x for each ten symbols cleared, whether by cascades or by exploding scatters. The base game wipes it after every spin. Free Spins keep it running from the first spin of the round to the last, and our best round finished with the counter at 39x. Watch the row rather than the reels, and the design makes sense within a few spins.
What page 5 of 8 prints
The info screens carry the line most games hide. Page 5 of 8 prints a 96.50% theoretical RTP and gives each paid mode its own line: 96.51% under the Ante Bet, 96.49% on the standard buy, 96.51% on the Super buy. The maximum win is 5,000x the bet, a hard stop that closes the round the moment it is hit. The Ante Bet adds 25% to the spin for a doubled natural trigger chance, a standard ticket is priced at 65x, and a Super ticket at 400x with the counter pre-set to 50x. Our rounds all came from natural triggers. Every symbol value and every clause sits on the Alien Invaders rules page.
The session behind the review
ALIN-20260729-01 ran 2,798 spins at 2.00 and closed at 101,191.40 from a 100,000.00 start, a 121.29% return by money. Sixteen feature rounds came in, spaced 174 spins apart on average, and the best full round of the run paid 489.8x. The balance topped out at 101,345.60 on spin 1,684. A green session is luck, and the Alien Invaders review spends most of its length on why three green sessions in a row still do not make a promise. The session report prints the checkpoints and the round totals.
Demo credits and the real thing
We run every session on demo credits so the ledger can be published whole, and this page carries the same build. What we cannot check from outside is whether an operator runs the same 96.50% configuration, since variants exist, so read the info screen wherever money is involved. A third of spins pay something here, which feels friendly, while the money lives in rare retrigger rounds. The demo shows the first half of that sentence quickly and the second half slowly.

Neighbours on the shelf
The cascade family this build belongs to is set out on our cascade slots page, six tumbling builds with their trigger clocks and compounders side by side. The Demo Shelf holds every build we have logged, and the studio's other titles here are on the Pragmatic Play page. The protocol is on the methodology page.
