All-Round Adler

Adler sees every silhouette of one rarity per round, in order: White in 1R → Green in 2R → Blue in 3R → Purple in 4R. By 4R, the only things still unseen on the board are golds and reds, and since the board fills from the top with no gaps, the empty slots left are exactly where the golds and reds sit.

1R — one of three. You barely know the board yet, so find red cells with Rarity (Large) or see high-value identities and board depth with Collectible (Large). On a Super Rush (gold ×2) board, the Gold total — it gives the doubled gold value in one go, so in most cases using the Gold total in 1R to look for an all-in opening is a fine strategy too. But on the same board others' defensive bids come out high too, so skipping the all-in and defending with a reasonably high bid is also sensible.

2R — whichever of Rarity (Large) or Collectible (Large) you didn't use in 1R. Rarity (Large) lands randomly across the whole board — ignore the cells that hit the White and Green you already know and look only at Blue, Purple, Gold and Red.

3R — lock in the gold value with the Gold total (if you used the Gold total in 1R, high-value identities with Collectible (Large) instead). Keep bidding low.

4R — read the empty slots. Once Purple opens, the empty slots left = gold and red. Of Size (Large) on 10, the silhouettes that land in the empty slots are the gold and red shapes (Radiant Scepter 5×1 · White Dragon King 1×4 · Antique Suitcase 3×2 · Antique Pendulum Clock 2×5 · Game Console 3×4 · Luminous Goblet 3×3).

5R — board value = Gold total + the reds you checked + purples (small). By 5R Adler knows almost the whole board, so bid the top price within the board value you calculated.

Don't use Gold slots — the 4R empty-slot shapes and Size (Large) show how much area the reds take.
