Estimate the weekly reload Rollify will credit for your wager volume — before it lands. Operators never publish the formula, so treat the result as the centre of a ±40% range.
The model: bonus ≈ wager × house edge × tier share (5% at entry tiers to ~18% at the top), with a profit-period haircut. Enter your typical weekly or monthly volume and the calculator walks the tiers Rollify actually publishes — the same structured data that powers our bonus comparison, not a guess.
In our dataset Rollify's program is listed as Weekly Lossback Bonus, unlocked from Level 10, with $2,500 lifetime wager, released via VIP Dashboard.
