• ✓Idea: the game is four steps in a row, not four games — the difficulty is carrying each step's answer into the next
• ✓The sign at the end of a row carries a picture AND a number — both have to be read
• ✓Every row has more holes than the sign asks for — otherwise filling it wins without counting
• ✓The seed tray holds more kinds than there are rows, so there are decoys — with an exact fit the signs need never be read
• ✓Watering swells the root and opens the leaves — a real function of how grown it is, not two pictures swapped
• ✓The order always asks for FEWER than was grown, so emptying the rows is never the answer
• ✓The till asks line by line and then the total, on a real keypad
• ✓A wrong total is answered with high-or-low, then with the sum written out as ฿6 + ฿6 + ฿6, and the third buys a breath — after which the counter is reset
• ✓verify:garden proves 6,000 mornings: no sign asks for more than the row holds, no order asks for more than was grown, and every order has at least one line that is a subset
• ✓Sound, Thai + English, and Grandpa Kham as the host
• ✓The six vegetables are painted — seedling and grown side by side on one sheet, cut on one scale and one soil line
• ✓If a painting goes missing the game falls back to that vegetable's drawn version, never a broken image
• ✓Its own till scene — a painted stall at the garden gate instead of a white card on the fieldplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
