Builder Beaver slot overview
Builder Beaver is one of RealTime Gaming's lighter themes: a beaver on a building site, set on a standard 5x3 grid with 25 betways. Behind the theme it has a fairly complete data sheet for an RTG game, with a reported RTP, a volatility rating and a progressive jackpot.
One gap stands out. The catalog we rely on gives no release date, so we can't place it in RTG's timeline. Everything else comes from the same third-party source, and RTG's own site couldn't be reached to confirm it.
Its headline number is the 62,500x listed top win, the largest fixed multiple among the slots we reviewed in this group. This page puts that figure next to the withdrawal rules that decide how, and how fast, any big win would reach you. See the rest of our RTG slot reviews for comparison.
A 96.5% RTP means the game is designed to return $96.50 for every $100 staked over a very large number of spins, leaving a 3.5% house edge. Some RTG games come in more than one RTP setting, so check the info screen at your casino to see which version it runs.
How the Builder Beaver features work
The catalog names four features but not their exact mechanics. Use the in-game paytable to confirm triggers, spin counts and symbol values. In general terms:
Wild: stands in for standard symbols to complete a win. More in our glossary entry on wilds.
Scatter: pays or triggers features wherever it lands; see scatter symbols.
Free spins: a bonus round inside the game at your triggering stake. This is not the same as a casino free spins promotion.
Progressive jackpot: a prize that grows with play until it's won; our data doesn't say how it's triggered or whether it's pooled.
The progressive and the 62,500x top prize are two different things. The jackpot changes in size, while 62,500x is the listed fixed maximum. Our progressive jackpots explainer covers how jackpots are funded.
Builder Beaver on a $50 budget at $0.25, $1 and $5
With a reported RTP, the cost math is straightforward. Expected loss = total staked × 3.5%.

On average, replaying wins until $50 is gone gives about $1,429 of total bets ($50 ÷ 0.035). Medium volatility suggests swings sit between the extremes, but individual sessions can still end quickly or run long. Part of each stake also feeds the jackpot.
If you want the most time with the game, $0.25 spins stretch $50 furthest. Our bankroll management guide and penny slots guide cover low-stakes play. Over time, the house edge means losses are the expected result.
The 62,500x Builder Beaver max win vs withdrawal caps
A 62,500x win is extremely rare, but it's worth knowing what would happen if it landed, because caps change the picture. Silver Oak's banking page sets weekly withdrawals from $2,500, and third-party reviews report $2,500 a week at Planet 7 and Royal Ace, plus $5,000 a month at Royal Ace.

Weeks and months are rounded up. A bonus max cashout can cut the amount itself: third-party reviews report $1,000 on Planet 7's WELCOME200 match and 10x the deposit at Royal Ace. Silver Oak's offer page says no max withdrawal. Read max cashout explained and weekly withdrawal limits.
It depends on your state. Real-money online casinos are licensed in New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut and Rhode Island only, and RTG titles are mostly offered by offshore casinos. Our page on can I get in trouble for playing online casinos sets out what the law says.
Offshore casinos aren't licensed or regulated by any US state: there's no state regulator to complain to and no state protection of balances. The Michigan Gaming Control Board named Silver Oak and Planet 7 as illegal offshore operators in its April 9, 2025 release (opens in a new tab).
Where to play the Builder Beaver slot
These partners run RTG games: Silver Oak's mobile page names Realtime Gaming, and third-party reviews list RTG and SpinLogic at Planet 7 and Royal Ace. None of our sources confirms Builder Beaver in their lobbies, so check. All three are offshore and not licensed by any US state; check your state's law first.
Silver Oak Casino: $2,500 Welcome Bonus + 50 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Silver Oak's own pages conflict on wagering: the offer page says 30x and the general terms say 40x for slots (60x for table games and video poker). The offer page says there's no max withdrawal, deposits start at $30 on the banking page, and the site advertises a different package from our link, so check the terms at sign-up. See our Silver Oak review. Silver Oak's terms list progressives among the games excluded from bonus play.
Planet 7 Casino: $2,750 Welcome Bonus + 45 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Third-party reviews (not the casino's own pages) report 30x (bonus + deposit) wagering on slots, a $1,000 max cashout and a $30 card minimum for Planet 7's WELCOME200 match. Sources conflict on the details, so confirm at sign-up. Read the Planet 7 Casino review.
Royal Ace Casino: $2,500 Welcome Bonus + 35 Free Spins, via our link (new players, 21+ or 18+ where allowed, terms apply). Royal Ace's own terms weren't readable for this page. Third-party reviews report 30x (bonus + deposit) on slots, 60x on blackjack and video poker, a max cashout of 10x the deposit and $30 card minimums, and they disagree on the package itself, so check the terms at sign-up. See our Royal Ace review.

Frequently asked questions
What is the RTP of Builder Beaver?
Third-party catalog data reports a 96.5% RTP for Builder Beaver. That's a house edge of 3.5%, or an average cost of $1.75 for every $50 staked. RTG's own site couldn't be checked, and some RTG games come in more than one setting, so confirm the figure on the info screen at your casino. Our guide to how slot RTP works explains what the percentage does and doesn't tell you.
What is the max win on Builder Beaver?
The listed fixed top prize is 62,500x your bet, from the attributes table of third-party catalog data. That's $15,625 at $0.25 a spin, $62,500 at $1 and $312,500 at $5. Hitting it is extremely unlikely. At a $2,500 weekly withdrawal cap, a $62,500 win would take 25 weeks to cash out. Read our explainer on max cashout rules for how bonuses can limit it further.
When was Builder Beaver released?
Its release date isn't published in the sources we checked. The third-party catalog that supplies its other specs leaves the date blank, and RTG's site wasn't reachable. That doesn't change how the game plays, but it means we can't say where it sits among RTG's other titles. For dated RTG releases, browse our slot reviews hub, which lists release dates where they're known.
Is Builder Beaver high volatility?
No, third-party catalog data rates it medium volatility. That generally means a mix of smaller regular wins and occasional larger ones, between the steady feel of low-volatility games and the long dry spells of high-volatility ones. It's still a slot with a house edge, so sessions can end quickly. Our slot volatility guide explains how volatility and RTP work together.
Does Builder Beaver have a progressive jackpot?
Yes, the catalog lists a progressive jackpot alongside free spins, wilds and scatters. Our data doesn't describe the trigger or say whether the jackpot is pooled across casinos, so check the info screen. Progressive slots are excluded from bonus play at some casinos, including under Silver Oak's terms. See what a progressive jackpot is for the basics.
Can I play Builder Beaver with a bonus?
Possibly, but check first. Because it has a progressive jackpot, some casinos exclude it from bonus wagering; Silver Oak's terms list progressives among excluded games. Where it's allowed, also check max bet and max cashout, since a cap can limit what you keep from any win. Our guide to how to clear a casino bonus walks through the conditions.
Where can I play Builder Beaver in the US?
It's an RTG slot, so you'll mainly find it at offshore casinos running RTG or SpinLogic software rather than at state-licensed casinos. Our sources don't confirm it at any named partner, so search the lobby before you deposit. Offshore casinos aren't licensed by any US state, and your state's law decides whether playing there is permitted. Our best RTG casinos page lists partners that run the software.
Can I play Builder Beaver on my phone?
Yes, where a casino carries it, Builder Beaver plays in a mobile browser on iPhone or Android rather than through a store app. Silver Oak's mobile casino page describes browser play on phones and tablets with no dedicated app, and third-party reviews say Planet 7 works the same way. The 5x3 grid and 25 betways fit a phone screen comfortably, but open the info screen to confirm the RTP setting, since it can be harder to spot on mobile. Our playing on Android guide and the Silver Oak mobile page have more.
What is the minimum deposit to play Builder Beaver?
The minimum deposit depends on the casino, not the game, and at the partners on this page it starts around $30. Silver Oak's banking page lists $30 minimums for Bitcoin, Litecoin, Ethereum and cards, with card fees of 3% to 10%. Third-party reviews report $30 card minimums for the welcome matches at Planet 7 and Royal Ace. Once funded, Builder Beaver itself can be played at small stakes, so a $30 deposit at $0.25 a spin gives 120 spins before any wins. See what is the minimum deposit and our best low deposit casinos.
How much will I lose playing Builder Beaver over time?
At the reported 96.5% RTP, Builder Beaver is designed to keep about $3.50 of every $100 you stake over the long run. That works out to roughly $35 on $1,000 of total bets and $175 on $5,000. Your actual result in one session can be far better or worse, because medium volatility still produces swings. The figure that matters is total staked, not your deposit: replaying wins raises it. Part of each stake also funds the progressive. Our casino math basics guide and the house edge glossary entry show the formula.
Is Builder Beaver better than Lion's Lair?
On listed numbers, Lion's Lair has the edge, with a reported 97.5% RTP against Builder Beaver's 96.5%, and both are medium volatility with a progressive jackpot. That one-point gap means about $25 expected loss per $1,000 staked on Lion's Lair versus $35 on Builder Beaver. Builder Beaver uses 25 betways to Lion's Lair's 20, and it lists a 62,500x fixed top prize. Both figures come from the same third-party catalog, so confirm each game's info screen at your casino. Read our Lion's Lair review or the high RTP casinos list.
Is Builder Beaver rigged?
There's no evidence Builder Beaver is rigged; it's a RealTime Gaming title that uses a random number generator, so each spin is independent. The reported 96.5% RTP describes the long-run average, and the 3.5% house edge is how the game makes money without any need to manipulate results. The real uncertainty lies with the casino: offshore sites aren't checked by any US state regulator, and RTG's own certification couldn't be confirmed for this page. Our answers on are slots rigged online and how RNGs work explain the details.
Is Builder Beaver legal to play in Florida?
No, Florida doesn't license online casinos, so real-money Builder Beaver play has no legal state channel there. The Florida Gaming Control Commission says unauthorized casino-style games are criminal under sections 849.08 and 849.15, and in February 2025 it demanded that overseas casinos and bookmakers stop serving Floridians. The only lawful online sportsbook in the state is the Seminole Tribe's Hard Rock Bet. RTG games reach Florida mostly through offshore casinos that no US state regulates. Read can I play online casinos in Florida and our Florida state guide.
Do I have to pay taxes on Builder Beaver winnings?
Yes, Builder Beaver winnings are taxable federal income, whatever their size. A single slot win of $2,000 or more paid in 2026 meets the IRS Form W-2G threshold, which on a $1 spin means a 2,000x hit. Offshore casinos may not send a W-2G, but you still report the income on your return. From tax year 2026 the deduction for losses is reported to be capped at 90% of losses, so check IRS guidance. Keep dated records of deposits and withdrawals. Our gambling taxes guide and keeping gambling records page help.
