How Medusa II Works on win188
Medusa II is a video slot with a fixed number of reels, pay lines, and symbol types. You set your stake by selecting your bet level and coin value, then spin. Each spin's outcome is determined by a certified random-number generator (RNG); our system records the result and credits or debits your balance within seconds. The game's return-to-player (RTP) percentage is published in the game rules (accessible in-game via the Info button); this represents the theoretical payout rate over thousands of spins.
Medusa II features a bonus round triggered by scatter symbols. When you land three or more scatters across the reels, free spins are awarded. During free spins, certain multiplier symbols may land, increasing your win payout. The free spin round cannot be re-triggered during itself, but each free spin counts as a full spin toward your session history and weekly turnover calculation on win188.
Session Tracking and Game History
Every time you spin Medusa II on win188, the spin is recorded in your account's Game History. You can view your session summary anytime by logging in and navigating to Account > Game History > Medusa II. Your session record shows: total spins in the session, opening and closing balance, net win or loss, and session duration. This record is created for transparency and audit purposes; you can use it to review your activity or contact support if you have questions about a specific outcome.
Medusa II and Your Welcome Offer
When you make your first deposit on win188, our system credits a welcome offer bonus to your account. This bonus applies to all slot games, including Medusa II. You can use the bonus balance to spin Medusa II immediately; each spin is deducted from your bonus balance first, then your real balance once the bonus is exhausted. Your winnings from bonus spins are credited to your real balance once the bonus turns over (i.e., you've wagered the bonus amount plus your deposit a combined number of times as specified in the promotion terms).
To view your welcome offer terms, log in to win188 and navigate to Account > Promotions. You'll see the bonus amount, the turnover requirement, and the deadline for using the bonus. If you meet the turnover before the deadline, your bonus converts to withdrawable cash. If the deadline passes, any remaining bonus balance expires and is removed from your account.
Weekly Cashback and Medusa II Turnover
Every Monday morning, we calculate your net turnover for the previous seven days (Monday–Sunday, UTC+7) across all slot games, including Medusa II. Net turnover is your total stake volume minus your total winnings returned. For example, if you wagered our welcome offer on Medusa II last week and won our welcome offer, your net turnover is our welcome offer. Your cashback percentage depends on your current tier (Bronze, Silver, Gold, Platinum); higher tiers earn higher cashback rates. The cashback is calculated and credited to your account automatically on Monday; you do not need to claim it manually.
Cashback credit carries no wagering requirement—it's immediately withdrawable or usable on new spins. Many players on win188 use their weekly cashback to fund their Medusa II play during the following week, creating a cycle of consistent engagement and reward.
Tier Progression Through Medusa II Play
Your tier on win188 is determined by your cumulative monthly turnover. The more you spin Medusa II (and other games), the higher your tier at the end of the month. Each tier unlock increases your weekly cashback percentage, grants you bonus odds on certain games, and offers faster withdrawal processing. Bronze is the starting tier; Silver requires a small turnover threshold; Gold requires more; Platinum is reserved for high-volume players. Your tier resets on the first day of each calendar month, and new tier benefits are applied that same day.
Referral Rewards and Medusa II
We incentivize player referrals through a commission structure that applies across all games on win188, including Medusa II. When you refer a friend and they sign up and deposit, we credit a referral bonus to your account. The referral bonus is promotional balance that you can use to spin Medusa II, play other slots, or use on live-dealer tables. Your referred friend also receives a welcome bonus to their account, creating mutual benefit. To refer a friend, navigate to Account > Referral, copy your unique link, and share it via email or messaging. Your friend clicks the link, creates an account, and deposits; once their deposit clears verification, we credit your referral bonus within 24 hours.
