Monster File

Monster File Overview

Monster File is a 5-reel, 3-row video slot from KA Gaming, released on 28 June 2023. It has 20 paylines, marked on both sides of the reels, and stakes from 0.20 to 300 per spin. SlotCatalog lists a 96% RTP with RTP ranges; volatility and maximum win are not published.

The Kids and the Monster Symbols

The theme is a group of kids chasing monsters on a stormy night, with lightning around the reel frame. Four kid characters are the premium symbols: a blond boy with a bat, a girl in a green jacket with a walkie-talkie, a boy in a red cap and a girl with a headset. Below them sit a pink demon-flower emblem, a blue medallion and the card ranks A, K, Q, J and 10. A character symbol marked WILD substitutes on the reels, and an orange monster symbol marked SCATTER pays anywhere on the grid.

Paytable at a $300 Bet

The paytable screen was captured at the maximum total bet of $300 ($15 per line). Values for five, four and three of a kind, with the five-of-a-kind multiple of the total bet:

• blond boy – $4,500 / $2,250 / $1,200 (15x)
• green-jacket girl – $3,750 / $1,500 / $900 (12.5x)
• red-cap boy – $2,700 / $1,200 / $750 (9x)
• headset girl – $2,250 / $750 / $450 (7.5x)
• demon-flower – $1,500 / $600 / $375 (5x)
• blue medallion – $1,200 / $450 / $225 (4x)
• A – $900 / $375 / $150 (3x)
• K – $600 / $300 / $150 (2x)
• Q – $450 / $225 / $120 (1.5x)
• J – $300 / $150 / $75 (1x)
• 10 – $150 / $75 / $45 (0.5x)

The gap between the groups is wide. Five blond boys pay 30 times as much as five 10s, and even three of the top symbol ($1,200) beat five of any card rank. Three of a kind of the card ranks returns less than the $300 stake, so the kids carry the game.

How the Lines Pay

All 20 lines are always active, so the total bet is 20 times the line bet: the $0.20 minimum is $0.01 per line and the $300 maximum is $15 per line. Line wins are paid per line from the left, so five blond boys on one line are worth 300 times the line bet. When several lines win on the same spin, the banner at the top reports them one by one (“Line 15 wins $1,200”) before the total is added up.

Scatter wins are counted separately from the lines. In our four-scatter spin three of them sat on the top row of reels 1, 3 and 5 and one in the middle of reel 4, and the game paid them as one “Scatter wins $600” award.

Our Wins

All our spins were played at $300. Three demon-flowers on line 19 paid $375, exactly the paytable value. Four scatters in one spin paid a $600 scatter win, which is 2x the total bet. The best moment was a Huge Win of $2,400 – 8x the stake – with line 15 alone paying $1,200 while gold coins rained over the reels.

Free Spins

SlotCatalog lists free spins with a multiplier and extra spins during the round among the game’s features, triggered by the scatter. Our screenshots do not show the round itself, so we do not quote the number of spins or the multiplier.

Controls

The bottom bar keeps it simple: New Bet to change the stake, a large play button that you can hold for Autoplay, Max Bet, and the win, total bet and balance displays. The demo starts with a $100,000 play balance.

Who It Is For

Monster File suits players who like a classic 20-line slot with a clear paytable. The character symbols pay well at five of a kind, and the scatter pays on its own even without the bonus round.
