The Brain Behind StackedSlips

About AngieMantis

I built this site because I couldn't find one honest, no-fluff resource for finding the best DFS and betting apps with real referral codes. So I made it myself.

Hi, I'm Angie 👋

I'm a sports bettor, DFS grinder, and content creator who's spent years testing every app, chasing every bonus, and figuring out where the real value hides. StackedSlips is my way of sharing everything I've learned — no fluff, no paid placements, just the platforms I actually use and the codes that actually work.

Every single link on this site is my personal referral. Every single review is my honest opinion. I don't list anything I haven't personally signed up for, deposited money into, and tested for at least a few weeks. When I say something's good, I mean it — and when I think something's overrated, I'll tell you that too.

The goal is simple: help you collect every bonus you're entitled to from Day 1, and put you on the apps where your money has the best shot of growing.

How I Test Every App

Step 1

Sign Up & Deposit

I create a real account, use my own referral code, and make a real deposit.

Step 2

Claim the Bonus

I actually claim the sign-up bonus and verify it gets credited correctly.

Step 3

Bet for 2–4 Weeks

I place real bets and track the experience: odds quality, UX, and stability.

Step 4

Test Withdrawal

I withdraw funds and note the speed, fees, and any friction involved.

Step 5

Write My Review

Only then do I write the review — based entirely on my real experience.

Step 6

Monitor for Changes

I revisit codes and bonuses regularly to make sure everything stays accurate.
