Reroute Tower Defense merge, ranks and upgrade cards

Checked 2026-11-10

The Android title is Reroute: Merge Tower Defense because two towers of the same type and the same level become one stronger tower of that type.

The merge rule

Google Play states it directly: merge two towers of the same type and level into a stronger one. Field merges have no level cap. You can move or swap towers and rebuild the maze at any time. The LogixGenic run shows towers from level 1 through level 11 on the field at once, which fits “no cap” without proving what the highest level is. Different types do not merge. The listing only allows the same type.

Shop level is not field level

The shop sells a tower at a shop level. Upgrade cards name a tower and a shop level, such as Shop Lv. 2 on the official art and Shop Lv. 6, 4 and 3 in the video. Play says you choose an upgrade or a perk card after every wave. The store screenshot also shows Claim All, so “pick one” and “take all” are both visible and I will not collapse them into one rule. A card raises the level the shop offers next. It does not add a level to a tower you already placed. Merging is how a placed tower goes up.

Ranks from Recruit toward Legend

Play names the two ends: Recruit and Legend. The video shows badges reading Recruit, Scout, Guardian, Knight and Commander, with a bar that fills as the level number climbs. I do not know whether those five are the full ladder, or whether names sit between Commander and Legend that this run never reached. The list below is not a complete rank table.

One filmed rank-up granted a large coin amount. I am not printing that amount as a formula, because a single popup is not a table. Chests in the store art and the video include a coin chest, a card chest, and a +1 level chest. The shop’s round arrow costs 5 coins in the video. I still treat its job as unconfirmed. Sell exists and returns some coins; the rate is unpublished. Tower-by-tower prices that were readable sit on the tower page.

There is no perk catalog beyond the sentence “upgrade or a perk card.” Card faces in the video show a row of pink and grey diamonds. I do not know what the diamonds mean, so I do not explain them. If you are deciding whether to merge or to buy, the public rule is only: same type, same level, no field cap, and the road can be rebuilt by dragging. The how to play page is the place for path shape.
