Look for two of the first three reels to be one coin away from turning wild, plus at least one additional coin in the "Bad Zone" (reels 4 and 5); alternatively, any machine with four or five coins total across the board is a go.
Count the BUDDHA SYMBOLS collected on each reel. Look for 4 Buddhas on any reel (turns that reel WILD for 4 spins). Left reels matter most (Reel 1 > 2 > 3 > 4 > 5). Good news: progress never decreases, and each bet level has separate Buddha progress.
Visible coin counter or meter on the cabinet showing collection progress. Higher progress = closer to a 3-level stand-alone progressive trigger = more potential value to the next player. Verify the bet level the meter was built at — persistent state typically applies per bet level. Variants include Pharaoh's Power and Radiant Witch.
Identify a counter in the lower right corner showing three or more daggers, or the rising rope on the left side of the screen having a flag nearly unfurled at the very top.
Count the HEIGHT of reels 2, 3, and 4. Calculate WAYS TO WIN using the formula: 4 × R2 × R3 × R4 × 4. Only play at ≥3,136 ways (or ≥2,688 ways if Super Stampede is visible). Skip if below 3,136 ways with no exceptions.
Check the progressive meter values and calculate expected value (EV) based on how close each jackpot is to its Must-Hit-By cap. Look for meters near their maximum thresholds.
Analyze the progressive jackpot meters to identify favorable EV situations. Look for meters approaching their Must-Hit-By thresholds for optimal play opportunities.
Check the W-I-L-D letters above each reel. Look for 4 letters lit on any reel (turns that reel WILD for 4 spins). Left reels matter most (Reel 1 > 2 > 3 > 4 > 5). Good news: progress never decreases, and each bet level has separate lamp progress.
Check the COIN COLUMNS above each reel. Look for columns 1 coin from full (especially with Win All/Wheel coins), or multiple columns 70-90% full. Win All or Wheel coins in near-full columns are priority plays. Skip if all columns are mostly empty.
Check the COIN COLUMNS above each reel. Look for columns 1 coin from full (especially with WIN ALL/Wheel coins), or multiple columns 70-90% full. WIN ALL, Wheel, or 10x+ multiplier coins are priority plays. Skip if all columns are mostly empty.
Check the THREE METERS (Red, Green, Blue) above the reels. Each must hit by 15 free games. Play Red at ≥12, Green at ≥13, Blue at ≥14. Remember: check ALL bet levels as each has separate meters!
Check the pink/red BRAIN METER at the top of the screen. Bonus triggers at 500 points. Look for 200+ points (standard threshold) or 150+ in competitive areas. Note: Each bet level has a separate meter, and the meter can decrease (-12 points when no brain appears).
