Equation: CORAL + MAROON + SALMON = COLORS. Each of the 8 unique letters (A, C, L, M, N, O, R, S) represents a different digit. Leading letters (C, M, S) cannot be zero.

C=5, O=0, R=9, A=7, L=6, M=1, N=8, S=2 → 50976 + 179008 + 276108 = 506092

Difficulty: medium · Category: addition · Unique letters: 8

This medium-level addition alphametic puzzle features 8 unique letters (A, C, L, M, N, O, R, S). In the equation CORAL + MAROON + SALMON = COLORS, each letter maps to a distinct digit from 0 to 9. With only 8 of 10 digits used, 2 digits remain unused in the solution. The leading letters C and M and S cannot represent zero — this is your first constraint. This puzzle has 3 addends (CORAL + MAROON + SALMON), making carry analysis more complex. Start from the rightmost column and work left, tracking carries between columns.

This addition alphametic has 8 unique letters to determine.
Leading letters: C, M, S. None of these can be zero.
There are 8 unique letters, so 2 digits from 0–9 will not be used.
Start from the rightmost column (units place) and work left, tracking carries between columns.
With three addends, each column can produce a carry of at most 2.
A moderate number of letters means you'll need logical deduction alongside trial and error.
